Decrease writes to local variables in Buffer.MemoryCopy (#6627)
In `Buffer.MemoryCopy` currently we are making 4 writes every time we copy some data; 1 to update `*dest`, 1 to update `dest`, 1 to update `src` and 1 to update `len`. I've decreased it to 2; one to update a new local variable `i`, which keeps track of how many bytes we are into the buffer. All writes are now made using
```cs
*(dest + i + x) = *(src + i + x)
```
which has no additional overhead since they're converted to using memory addressing operands by the jit.
Another change I made was to add a few extra cases for the switch-case at the beginning that does copying for small sizes without any branches. It now covers sizes 0-22. This is beneficial to the main codepath, since we can convert the unrolled loop to a `do..while` loop and save an extra branch at the beginning. (max 7 bytes for alignment, 16 for 1 iteration of the loop, so the min bytes we can copy without checking whether we should stop is 23.) This adds
This PR increases the performance of `MemoryCopy` by 10-20% for most buffer sizes on x86; you can see the performance test/results (and the generated assembly for each version) [here](https://gist.github.com/jamesqo/
337852c8ce09205a8289ce1f1b9b5382). (Note that this codepath is also used by `wstrcpy` at the moment, so this directly affects many common String operations.)

Null check folding.
1. Added a null check folding optimization to early prop. The optimization tries to fold
GT_NULLCHECK(y) nodes into GT_IND(x) nodes where x=y+const
in the same block (where const is sufficiently small). The algorithm uses SSA use-def info
to go from x to its def and then tries to match the pattern x = COMMA(NULLCHECK(y), ADD(y, const))).
If such a pattern is found, the algorithm checks the trees and statements that are between the use
and the def in execution order to see if they have unsafe side effects: calls, exception sources, and
assignments (all assignment if we are in a try and assignments to global memory if we are not).
If there are no nodes with unsafe side effects, the null check is removed.
2. Made several improvements to null check elimination in assertion propagation.
..* Added a new kind for op1: O1K_VALUE_NUMBER
..* Non-null assertions can now be made about arbitrary value numbers, not just locals
..* Fixed code that was trying to find a ref given a byref: the code now handles an arbitrary number of
offsets and checks whether the total offsetof is small enough.
..* Added similar code that tries to find a ref VN given a byref VN

Implement GcInfo v2
Ref #4379
This change implements GcInfo version 2 for all platforms that use the
GcInfo library (all architectures other than X86).
Changes are:
1) Defines ReturnKind enumeration for all platforms
2) Change the GcInfo encoder library to encode the ReturnKind and ReversePInvokeFrame slot
3) Change the CM's GcInfo decoder to encode the ReturnKind and ReversePInvokeFrame slot for GCINFO_VERSION 2
4) Some corrections to GCINFO_MEASUREments
5) Changes to RYU Jit to provide the correct information to the encoder
6) Changes to the VM to use the ReturnKind information while hijacking a thread
- If ReturnKind is available from GcInfo, new hijack routines are used
- Otherwise, fall back to old method (for compatibility)
7) Rework and simplify the thread hijack routines by scanning HijackFrames directly for gcroots
8) Supporting code to implement the above features.
Returning Structs in multiple registers
Hijacking for StructInRegs is currently only implemented for
Unix SystemV ABI Multi-reg struct returns. However, the hijack-workers that use
ReturnKind are ready to handle other platforms (ex: ARM/ARM64 Windows)
once the corresponding HijackTripThread() assembly routines are defined.
The New feature flag: FEATURE_MULTIREG_RETURN is set for platforms where a struct value
can be returned in multiple registers [ex: Windows/Unix ARM/ARM64, Unix-AMD64]
FEATURE_UNIX_AMD64_STRUCT_PASSING is a specific kind of FEATURE_MULTIREG_RETURN
specified by SystemV ABI for AMD64
Compatibility with other JITs
- All new GCInfo generated by RYU Jit is in GcInfo version 2
- All Ngen images must be regenerated with the new GcInfo version.
- Ready-to-run images with old GcInfo will continue to work.
- Jit64/X64 uses the GcInfo library, so it generates GcInfo version 2.
However, it doesn't (yet) provide the data to encode the correct ReturnKind
Similar is the case for ARM32 code running on JIT32, and any other JITs
that may be using GcInfo library but not yet modified to use the new API.
So, compatibility is achived using RT_Unset flag.
When ReturnKind is RT_Unset, it means that the JIT did not set
the ReturnKind in the GCInfo, and therefore the VM cannot rely on it,
and must use other mechanisms (similar to GcInfo ver 1) to determine
the Return type's GC information.
Implement GC root scanning for Hijack-frames
This change implements GCScanRoots() method for Hijacke-frames
based on the ReturnKind information available from the GcInfo.
If the exact ReturnKind is not available in the GcInfo, the
thread-suspension logic will compute the ReturnKind based on
the method-signature.
As a result of this change, several hijack-helpers in the VM
are cleaned up. There's only one implementation of HijackWorker()
to handle all returnKinds.
This change also simplifies the thread-hijack logic by using a
single assembly helper OnHijackTripThread() in most cases.
The only other helper used is for X86 floating point return values
for save/restoring the top of the FP stack.
ARM64
Only GcIndfo v2 is reliably supported for ARM64 platform.
The changes to thread-hijack mechanism fixes #6494 for ARM64.
No measurable change in JIT throughput, performance or native-image
size from this change.

Allow inlining when inlinee has `starg`
The inliner's restriction that methods that make use of the `starg` opcode
cannot be inlined is somewhat artificial. The comments indicate that the
reason for this excluion is because the inliner forward-substitutes
argument expressions in place of parameter references, but the codepaths
required to force evaluating an argument expression at the callsite and
reference that result in place of parameter references is already in place
to handle `ldarga` and complex argument expressions.
This change
- adds an `argHasStargOp` flag to the `inlArgInfo` type, similar
to the existing `argHasLdargaOp` flag
- removes the `CALLEE_STORES_TO_ARGUMENT` inline observation and instead
sets the new flag for `starg` cases
- updates `impInlineFetchArg` to force evaluation to a temp for arguments
that are marked `argHasStargOp`
- updates `starg` processing in the importer to store to the
corresponding temp when importing for an inlinee

the parent comma, because the rewrite involves the comma as well. The
code currently has a bug in that its check for whether the bounds check
is redundant also occurs when processing reaches the comma, which is wrong
because the assertion set may then include assertions generated by the RHS
of the comma (there is code to compensate for the assertion generated by
the bounds check itself, which is the LHS of the comma, but no compensation
for the RHS).
This change moves the analysis of whether bounds checks are redundant to
the proper spot in the processing order, and delays only the rewrite to
the processing of the comma; the redundancy of the bounds check is
communicated via a new opcode-specific flag: GTF_ARR_BOUND_INBND.
Fixes #6318.

Swallow exception in gc_heap::fire_etw_allocation_event (#6571)
The gc_heap::fire_etw_allocation_event calls TypeHandle::GetName that can throw
due to OOM. But we don't want failures to fire event cause a failure during the GC,
so such exception should be swallowed and no event fired in such case.
This was discovered as a contract failure during test runs with ETW logging enabled
when this function was transitively called from Thread::PerformPreemptiveGC which
was recently modified to have NOTHROW contract.
Interestingly, this was not detected by the static contract checker.

Replace the LSRA stack with a hash table.
LSRA currently uses a stack to find the `LocationInfo` for each register consumed
by a node. The changes in this stack's contents given a particular node are
governed by three factors:
- The number of registers the node consumes (`gtLsraInfo.srcCount`)
- The number of registers the node produces (`gtLstaInfo.dstCount`)
- Whether or not the node produces an unused value (`gtLsraInfo.isLocalDefUse`)
In all cases, `gtLsraInfo.srcCount` values are popped off of the stack in the
order in which they were pushed (i.e. in FIFO rather than LIFO order). If the
node produces a value that will be used, `gtLsraInfo.dstCount` values are
then pushed onto the stack. If the node produces an unused value, nothing is
pushed onto the stack.
Naively, it would appear that the number of registers a node consumes would be
at least the count of the node's non-leaf operands (to put it differently, one
might assume that any non-leaf operator that produces a value would define at
least one register). However, contained nodes complicate the situation: because
a contained node's execution is subsumed by its user, the contained node's
sources become sources for its user and the contained node does not define any
registers. As a result, both the number of registers consumed and the number of
registers produced by a contained node are 0. Thus, contained nodes do not
update the stack, and the node's parent (if it is not also contained) will
pop the values produced by the contained node's operands. Logically speaking,
it is as if a contained node defines the transitive closure of the registers
defined by its own non-contained operands.
The use of the stack relies on the property that even in linear order the
JIT's IR is still tree ordered. That is to say, given an operator and its
operands, any nodes that execute between any two operands do not produce
SDSU temps that are consumed after the second operand. IR with such a
shape would unbalance the stack.
The planned move to the LIR design given in #6366 removes the tree order
constraint in order to simplify understanding and manipulating the IR in the
backend. Because LIR may not be tree ordered, LSRA may no longer use a stack
to find the `LocationInfo` for a node's operands. This change replaces the
stack with a map from nodes to lists of `LocationInfo` values, each of
which describes a register that is logically defined (if not physically
defined) by that node. Only contained nodes logically define registers that
they do not physically define: contained nodes map to the list of
`LocationInfo` values logically defined by their operands. All non-contained
nodes map to the list of `LocationInfo` values that they physically define.
Non-contained nodes that do not define any registers are not inserted into
the map.
