Alex Richardson 7dc3136033 [llvm-readobj] Add support for decoding FreeBSD ELF notes
The current support only printed coredump notes, but most binaries also
contain notes. This change adds names for four FreeBSD-specific notes and
pretty-prints three of them:

NT_FREEBSD_ABI_TAG:
This note holds a 32-bit (decimal) integer containing the value of the
__FreeBSD_version macro, which is defined in crt1.o and will hold a value
such as 1300076 for a binary build on a FreeBSD 13 system.

NT_FREEBSD_ARCH_TAG:
A string containing the value of the build-time MACHINE_ARCH

NT_FREEBSD_FEATURE_CTL: A 32-bit flag that indicates to the kernel that
the binary wants certain bevahiour. Examples include setting
NT_FREEBSD_FCTL_ASLR_DISABLE which tells the kernel to disable ASLR.

After this change llvm-readobj also no longer decodes coredump-only
FreeBSD notes in non-coredump files. I've also converted the
note-freebsd.s test to use yaml2obj instead of llvm-mc.

Sam McCall 46cc7ce35a [clangd] Add semanticTokens modifiers for function/class/file/global scope
These allow (function-) local variables to be distinguished, but also a

It's not quite independent with existing information (e.g. the

Tobias Gysi 5fa893cc38 [mlir] add support for verification in integration tests
The patch extends the runner utils by verification methods that compare two memrefs. The methods compare the content of the two memrefs and print success if the data is identical up to a small numerical error. The methods are meant to simplify the development of integration tests that for example compare optimized and unoptimized code paths (cf. the updates to the linalg matmul integration tests).

Sam McCall dd8fb21227 [clangd] Implement semanticTokens modifiers
- Infrastructure to support modifiers (protocol etc)
- standard modifiers:
  - declaration (but no definition, yet)
  - deprecated
  - readonly (based on a fairly fuzzy const checking)
  - static (for class members and locals, but *not* file-scope things!)
  - abstract (for C++ classes, and pure-virtual methods)
- nonstandard modifier:
  - deduced (on "auto" whose Kind is Class etc)
    Happy to drop this if it's controversial at all.
- While here, update sample tweak to use our internal names, in
  anticipation of theia TM scopes going away.

This addresses some of the goals of D77702, but leaves some things undone.
Mostly because I think these will want some discussion.
 - no split between dependent type/name.
   (We may want to model this as a modifier, type+dependent vs ???+dependent)
 - no split between primitive/typedef.
   (Is introducing a nonstandard kind is worth this distinction?)
 - no nonstandard local attribute
   This probably makes sense, I'm wondering if we want others and how
   they fit together.

There's one minor regression in explicit template specialization declarations
due to a latent bug in findExplicitReferences, but fixing it after seems OK.

This can be reproduced by running the new `modernize-use-nullptr-cxx20.cpp` test without applying the supplied patch to `UseNullptrCheck.cpp`; the current clang-tidy will mistakenly replace:
```result = (a1 < a2);```

Lei Zhang 4c640e49c9 [mlir][linalg] Verify indexing map required attributes
Indexing maps for named ops can reference attributes so that
we can synthesize the indexing map dynamically. This supports
cases like strides for convolution ops. However, it does cause
an issue: now the indexing_maps() function call is dependent
on those attributes.

Linalg ops inherit LinalgOpInterfaceTraits, which calls
verifyStructuredOpInterface() to verify the interface.
verifyStructuredOpInterface() further calls indexing_maps().
Note that trait verification is done before the op itself,
where ODS generates the verification for those attributes.
So we can have indexing_maps() referencing non-existing or
invalid attribute, before the ODS-generated verification
kick in.

There isn't a dependency handling mechansim for traits.
This commit adds new interface methods to query whether an
op hasDynamicIndexingMaps() and then perform
verifyIndexingMapRequiredAttributes() in
verifyStructuredOpInterface() to handle the dependency issue.

Nemanja Ivanovic a5222aa085 [DAGCombine] Do not remove masking argument to FP16_TO_FP for some targets
As of commit 284f2bffc9, the DAG Combiner gets rid of the masking of the
input to this node if the mask only keeps the bottom 16 bits. This is because
the underlying library function does not use the high order bits. However, on
PowerPC's ELFv2 ABI, it is the caller that is responsible for clearing the bits
from the register. Therefore, the library implementation of __gnu_h2f_ieee will
return an incorrect result if the bits aren't cleared.

This combine is desired for ARM (and possibly other targets) so this patch adds
a query to Target Lowering to check if this zeroing needs to be kept.

Jan Svoboda 40c261c41c [clang][cli] Generate and round-trip language options
This patch implements generation of remaining language options and tests it by performing parse-generate-parse round trip (on by default for assert builds, off otherwise).

This patch also correctly reports failures in `parseSanitizerKinds`, which is necessary for emitting diagnostics when an invalid sanitizer is passed to `-fsanitize=` during round-trip.

This patch also removes TableGen marshalling classes from two options:
* `fsanitize_blacklist` When parsing: it's first initialized via the generated code, but then also changed by manually written code, which is confusing.
* `fopenmp` When parsing: it's first initialized via generated code, but then conditionally changed by manually written code. This is also confusing. Moreover, we need to do some extra checks when generating it, which would be really cumbersome in TableGen. (Specifically, not emitting it when `-fopenmp-simd` was present.)
