JIT: add pass to merge common throw helper calls (dotnet/coreclr#27113)
Look for blocks with single statement noreturn calls, and try to reroute
flow so there's just one block call that all predecessors target.
Resolves dotnet/coreclr#14770.
Note this impairs debuggability of optimized code a bit, as it can change which
line of code apparently invokes a throw helper in a backtrace. But since we're
already commoning jit-inserted throw helpers (like array index OOB) this is not
breaking any new ground.
We could also handle commoning BBJ_THROW blocks, with some extra effort,
but prototyping indicates duplicate throws are pretty rare.
This phase runs just before `optOptimizeFlow`, so that we can leverage
the ref counts and predecessor lists to ensure we make correct flow updates.
It doesn't bother trying to clean out IR, that happens naturally as blocks
become unreferenced.
In some cases nothrow helpers end up being tail call candidates. We now suppress
tail calling noreturn methods if there is more than one such call site in the method,
hoping that instead we can merge the calls.

Add file creation method that takes an ACL (dotnet/corefxdotnet/coreclr#42099)
Approved API Proposal: dotnet/coreclr#41614
Related change for directory creation method that takes an ACL: dotnet/coreclr#41834 -merged and ported to 3.1 Prev2
Description
We have extension methods in System.IO.FileSystem.AclExtensions that let the user get and set ACLs for existing files, but we do not have methods that create files with predefined ACLs.
.NET ACL (Access Control List) support is Windows specific. This change will reside inside the System.IO.FileSystem.AccessControl assembly.
Customer impact
Before this change, customers had to create a file or filestream, then set its ACLs. This presents a few problems:
Potential security hole as files can be accessed between creation and modification.
Porting difficulties as there isn't a 1-1 API replacement
Stability issues with background processes (file filters) can prevent modifying ACLs right after creation (typically surfaces as a security exception).
This change addresses those problems by adding a new extension method that allows creating a file and ensuring the provided ACLs are set during creation.
This change is expected to be backported to 3.1.

Don't compare `this` with null.
* Variables 'm_Cost', 'm_Size' are initialized through the call to the same function. It's probably an error or un-optimized code. Consider inspecting the 'Expr()->GetCostSz()' expression.
* Parameter 'toRefPosition' is not used inside function body.
* Expression 'parentOfArgObj == parentArgx' is always true.

Support large EventSource filter args (dotnet/coreclr#27500)
1. Fix NullReferenceException. When the filter args exceeded the

The code previously asserted that data was not null and triggered NRE
when it was. The fix correctly null checks the value instead of
asserting and uses an empty args dictionary in this case, the same as if
filter args had been empty to begin with.
2. ETW has always limited filter args to 1024 bytes but EventPipe has no
such restriction. When using DiagnosticSourceEventSource it can be
useful to specify a larger filter arg blob. I can't do anything about
ETW's restriction but there is no need for the runtime to force
EventPipe to be equally limited. The larger size also reduces the chance
that we need to hit the fallback path above causing filter args to be
ignored.

Fix GCStress C issue with the fix to VS2019 optimization (dotnet/coreclr#27507)
* Fix GCStress C issue with the fix to VS2019 optimization
There is a place in the runtime that we hit during GCStress C and that
was creating uninitialized GCFrame and initializing it only
conditionally. In the GCFrame destructor, we always try to pop the
GCFrame out of the per-thread linked list and this was breaking it.
The fix is to always initialize the GCFrame. In the problematic place,
it was not being initialized / pushed on the linked list when number of
GC slots it was to protect was 0. But the logic in GCFrame works just
fine even in that case, so I've made the initialization over there
unconditional.
I've also made a couple of methods in the GCFrame private as they are
never supposed to be called from the outside, removed the default
GCFrame constructor so that noone can create uninitialized GCFrame
anymore and also removed placement new from GCFrame that doesn't seem to
have any purpose.
* Reflect more feedback
* Folded the Pop and Push functions into their callers
* Folded the Initialize to the constructor

CoreCLR pipeline optimizations (dotnet/coreclr#27059)
Today, R2R compilation of test MSIL using Crossgen happens during
test execution in Helix. This means that the managed artifacts for a
given OS / architecture / config combo are identical for a R2R /
non-R2R job. Additionally, we need very few artifacts for running
the CoreFX tests. In practice it turns out we only need to build the
test host. We can exploit these facts to further reduce the number
of test build jobs in CoreCLR pipelines.
Thanks

Switch Crossgen2 over to the new command-line parser (dotnet/coreclr#27489)
With this change, Crossgen2 passes basic validation. If possible,
I would love to be able to merge this in ASAP as it's of paramount
importance for our repo consolidation efforts. I'll be happy to
follow up cleaning this change as necessary.
1) Update to a newer version of the System.CommandLine.Experimental
package enabling more general binding syntax needed for unambiguous
binding of multi-value arguments vs. options.
2) Explicitly specify arity for multi-value options as for whatever
reason the default maximum is 255 (lower than the number of reference
assemblies in Core_Root, for instance).
3) Reference paths cannot be bound to FileInfo[] as their syntax
supports wildcards.

Implement struct marshalling via IL Stubs instead of via Field… (dotnet/coreclr#26340)
* First pass on adding support for byref field homes to il marshalers.
Remove dead code for calculating managed field size.
Add field IL marshal infra up to MarshalInfo::GenerateFieldIL.
Add preliminary changes for MarshalInfo ctor to have the logic handle field marshalling logic. Still need to handle WinRT struct field logic correctly.
First shot at handling fields of WinRT structs.
Cleanup
Clean up entrypoints
Fix cleanup marshal emit.
Disable specific paths on struct marshal stubs.
Implement emitting full struct marshalling stub.
Add StructMarshalInteropStub method name.
Add NDirect::CreateMarshalILStub
Get byvalue StructMarshalling/PInvoke tests passing excluding missing ILMarshalers (ByValArray and ByValTStr).
Correctly classify struct marshal stubs as struct marshal stubs instead of PInvoke stubs.
Implement UnmanagedType.ByValArray IL marshaler.
Implement ILMarshaler equivalent for ansi-char fixed arrays.
Fix parameter mismatch in Native->CLR direction for struct marshalling.
Implement ByValTStr marshalling. Support unaligned fields in IL stubs.
Load CleanupWorkList from param list if in a struct marshalling stub
Implement SafeHandle and CriticalHandle field marshalling in IL struct stubs
Fix handle field marshalers. Add error reporting in struct field IL marshalers consistent with old FieldMarshaler error reporting.
Convert Array-of-nonblittable-struct marshalling to use IL stubs.
Convert LayoutClass marshalling to use IL stubs.
Fix marshalling of LayoutClass fields in structs.
Add non-blittable fixed buffer assert in the struct IL stub path.
Implement Marshal APIs via the IL stubs.
Fix default char marshaler selection.
Move hidden-length-array marshalling over to struct marshalling stubs.
Convert struct marshal IL stub users to use helper that will automatically cleanup on failure to marshal.
Match MarshalInfo::MarshalInfo behavior to ParseNativeType for fields.
Remove old FieldMarshaler-based marshalling.
Fix signed/unsigned mismatch.
Fix IsFieldScenario on non-COMINTEROP plaforms
Fix off-Windows build.
Handle automatic partial cleanup of struct marshaling entirely within the struct stub.
Remove now-unused ValueClassMarshaler. Move DateMarshaler to managed since it doesn't need to be an FCall.
Error out on recursive struct definitions in the IL stub generation as we did in the field marshalling.
Remove FieldMarshalers and replace with a significantly simpler structure (NativeFieldDescriptor) that stores only the needed info for determining validity in WinRT, blittability, and calling convention classification.
This will save 4/8 bytes for every field in a non-auto-layout structure or class loaded into the runtime.
Add explicit test for recursive native layout.
Allow marshalling as UnmanagedType.Error on all platforms (on non-Windows the behavior matches UnmanagedType.I4).
Collapse common primitive marshalling cases together.
Disable WinRT parameter/retval-only marshalers in field scenarios.
Revert "Collapse common primitive marshalling cases together."

e73b78a5bca80009fb541f5119301329599a16ad.
Fix error marshalling off Windows for uint.
Disable LPStruct marshalling in structs.
Disable copy-constructor marshaler in the field scenario.
Match error messages between MarshalInfo::MarshalInfo and ParseNativeType in the field scenario.
Refactor managed-sequential check out of ParseNativeType.
Remove invalid MARSHAL_TYPE_GENERIC_U8 references.
Add override specifier.
Change ParseNativeType to use MarshalInfo::MarshalInfo to calculate field marshalling info instead of maintaining two native field classification functions.
Clean up native field categories. Remove nsenums.h since it is now unused.
Move CheckIfDisqualifiedFromManagedSequential to class.cpp.
Encapsulate stub flags for struct stubs. Read the BestFitAttribute once for the type instead of per field.
Fix perf regression in by-val arrays of non-blittable structures by caching the MethodDesc* to the struct stub in the "managed marshaler" structure. Now we have a perf improvement!
Fix memory leak in sig creation.
Keep compile-time information for struct stubs around as long as the owning loader allocator (instead of leaking).
Allocate the signature on the same heap as the IL stubs so it shares the same lifetime.
Fix build with fragile NGen support enabled so as to not break partners.
Add missing native field descriptors.
Fix clang build.
Only assert if we're emitting IL (so we don't assert during type-load).
Determine desciptor for pointer-sized fields based on target not host pointer size.
Don't emit IL stubs that call struct stubs into R2R images since there's not a good way for us to emit the token.
Fix tracing test failures.
Force field marshaling to not stackalloc.
Cache Sytem.RuntimeMethodInfoStub instances created in the VM in the MethodDesc's owning LoaderAllocator.
Struct marshal stubs don't have an MethodDesc context arg.
Copy FieldDesc on NFD assignment.
Fix initialization of stubMethodInfoCache lock owner.
Fix alignment calculation of decimal fields and decimal array fields in NFDs.
Fix Crst leveling.
Enable handling decimal-as-currency fields accurately off-Windows.
Fix deadlock where two threads are both trying to generate an IL stub for the same P/Invoke and one of the parameters needs a struct stub generated.
Fix incorrect check for if we need a struct marshal stub in some of the variant/array cases.
We never need to promote a field value to 8 bytes.
Fix issue with recursive pointer fields.
Shortcut blittable types in stubhelpers.
Use LDFTN + PREPARE_NONVIRUTAL_CALLSITE_USING_CODE instead of LDTOKEN + GetInternalToken.
