[mlir][spirv] Change translation to use spirv.module
Update the SPIRV `mlir-translate` translations to translate to/from
`spirv.module` instead of `builtin.module`. This simplifies the
translation since the code no longer needs to walk the module looking
for a SPIRV module, however it requires passing `-no-implicit-module` to

[AArch64] Allow users-facing feature names in clang target attributes
D133848 added support for the GCC format of target("..") attributes. The
supported formats to match gcc are:
// "arch=<arch>" - parsed to features as per -march=..
// "cpu=<cpu>" - parsed to features as per -mcpu=.., with CPU set to <cpu>
// "tune=<cpu>" - TuneCPU set to <cpu>
// "+feature", "+nofeature" - Add (or remove) feature.
We also support the existing formats, previously accepted by clang, for
compatibility with the existing code and intrinsics code:
// "feature", "no-feature" - Add (or remove) feature.
The clang formats would accept and use internal feature names
("fullfp16"/"neon"/"sve") as opposed to the user facing names
("fp16"/"simd"/"sve"). Usually they use the same names, but can be
different for cases like fp, fullfp16 and mte (among others).
This patch makes the clang format also except the user facing names, by
parsing the features through getArchExtFeature. There is a fallback if
the name is not recognized (like "fullfp16"), where we add the existing
string which should then be checked later for consistency. This allows
the internal names to be used as before, so long as they are recognized
as internal names. (Note that we currently don't have an implementation
of isValidFeatureName. The backend will currently give an error like
"'-sid' is not a recognized feature for this target (ignoring feature)."
This should be improved in a later patch once an implementation of
isValidFeatureName in clang is present).

The Assignment Tracking debug-info feature is outlined in this RFC:
https://discourse.llvm.org/t/
rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir
Overview
It's possible to find intrinsics linked to an instruction by looking at the
MetadataAsValue uses of the attached DIAssignID. That covers instruction ->
intrinsic(s) lookup. Add a global DIAssignID -> instruction(s) map which gives
us the ability to perform intrinsic -> instruction(s) lookup. Add plumbing to
keep the map up to date through optimisations and add utility functions
including two that perform those lookups. Finally, add a unittest.
Details
In llvm/lib/IR/LLVMContextImpl.h add AssignmentIDToInstrs which maps DIAssignID
* attachments to Instruction *s. Because the DIAssignID * is the key we can't
use a TrackingMDNodeRef for it, and therefore cannot easily update the mapping
when a temporary DIAssignID is replaced.
Temporary DIAssignID's are only used in IR parsing to deal with metadata
forward references. Update llvm/lib/AsmParser/LLParser.cpp to avoid using
temporary DIAssignID's for attachments.
In llvm/lib/IR/Metadata.cpp add Instruction::updateDIAssignIDMapping which is
called to remove or add an entry (or both) to AssignmentIDToInstrs. Call this
from Instruction::setMetadata and add a call to setMetadata in Intruction's
dtor that explicitly unsets the DIAssignID so that the mappging gets updated.
In llvm/lib/IR/DebugInfo.cpp and DebugInfo.h add utility functions:
getAssignmentInsts(const DbgAssignIntrinsic *DAI)
getAssignmentMarkers(const Instruction *Inst)
RAUW(DIAssignID *Old, DIAssignID *New)
deleteAll(Function *F)
deleteAssignmentMarkers(const Instruction *Inst)
These core utils are tested in llvm/unittests/IR/DebugInfoTest.cpp.

[mlir:PDL] Add support for DialectConversion with pattern configurations
Up until now PDL(L) has not supported dialect conversion because we had no
way of remapping values or integrating with type conversions. This commit
rectifies that by adding a new "pattern configuration" concept to PDL. This
essentially allows for attaching external configurations to patterns, which
can hook into pattern events (for now just the scope of a rewrite, but we
could also pass configs to native rewrites as well). This allows for injecting
the type converter into the conversion pattern rewriter.

are supposed to be pure. Some quotes from LangRef:

In this patch, we use `rdhwr` to get synci_step.
If synci_step is zero, it means that the hardware will maintain the coherence. We need to do nothing.
Then for r6+, `synci` is required to keep icache global.
So we can use `synci` to flush icache.
The ISA documents ask a `sync` and a `jr.hb` after `synci`.
For pre-r6, we can use cacheflush libc function, which is same on Linux and FreeBSD.

[Clang][Sema] Add -Wincompatible-function-pointer-types-strict
Clang supports indirect call Control-Flow Integrity (CFI) sanitizers
(e.g. -fsanitize=cfi-icall), which enforce an exact type match
between a function pointer and the target function. Unfortunately,
Clang doesn't provide diagnostics that help developers avoid
function pointer assignments that can lead to runtime CFI
failures. -Wincompatible-function-pointer-types doesn't warn about
enum to integer mismatches if the types are otherwise compatible, for
example, which isn't sufficient with CFI.
Add -Wincompatible-function-pointer-types-strict, which checks for a
stricter function type compatibility in assignments and helps warn about
assignments that can potentially lead to CFI failures.

[clangd] Rename QueryDriverDatabase.cpp to SystemIncludeExtractor.cpp

[clangd] Perform system include extraction inside CommandMangler
It needs to run after edits from config files are applied to
the compile command (because the config file may specify the
compiler), and before resolveDriver() runs at the end of
CommandMangler.
As part of this change, QueryDriverDatabase is renamed to
SystemIncludeExtractor and is no longer a GlobalCompilationDatabase.

[lld-macho] Ensure that chained fixups data comes first in __LINKEDIT
libstuff-based tools (e.g. `codesign` and `strip`) require
`__chainfixups` to be the first section in `__LINKEDIT`, and print a
"file not in an order that can be processed" error message if that is
not the case.

symbols which cause errors to ld --no-undefined-version. Use
-Wl,--undefined-version if available (gold, ld.lld, future GNU ld 2.40).
