[MLIR][Python] Support attribute definitions in Python-defined dialects (#183907)
This PR is quite similiar to
https://github.com/llvm/llvm-project/pull/182805.
We added basic support of attribute definitions in Python-defined
dialects, including:
- IRDL codegen for attribute definitions
- Attr builders like `MyAttr.get(..)` and attr parameter accessors (e.g.
`my_attr.param1`)
- Use Python-defined attrs in Python-defined operations

[libunwind][PAC] Defang ptrauth's PC in valid CFI range abort
It turns out making the CFI check a release mode abort causes many,
if not the majority, of JITs to fail during unwinding as they do not
set up CFI sections for their generated code. As a result any JITs
that do nominally support unwinding (and catching) through their JIT
or assembly frames trip this abort.

[clang][Sema] fix crash on __type_pack_element with dependent packs (GH180307) (#180407)
dependent pack expansions in __type_pack_element can result in
single-element template argument lists. When performing semantic
analysis for these builtins, the compiler needs to account for the
dependent expansions and handle them without triggering strict size
assertions. The patch adds this analysis and ensures we either defer
evaluation for dependent cases or report clear out-of-bounds diagnostics
instead of crashing
Ai was used for test generation and CI debugging

[AMDGPU] Make uniform-work-group-size a valueless attribute (#183925)
The "uniform-work-group-size" function attribute previously took a
string value of "true" or "false". Since presence alone can convey the
"true" semantics and absence can convey "false", the value is
unnecessary.
This patch converts it to a valueless string attribute: presence
indicates true, absence indicates false. For backward compatibility,
auto-upgrade logic is added in both UpgradeAttributes (bitcode) and
UpgradeFunctionAttributes: if the old value is "true", the attribute is
kept without a value; if "false", the attribute is removed.

All setters (Clang CodeGen, OMPIRBuilder, AMDGPUAttributor, ROCDL
translation) and readers (AMDGPUAttributor, AMDGPULowerKernelAttributes,
AMDGPUHSAMetadataStreamer) are updated accordingly. The attribute is
also documented in the AMDGPU LLVM IR Attributes table where it was
previously missing.
Revert "[NFC][Clang] Auto generate check lines for `clang/test/CodeGenOpenCL/cl-uniform-wg-size.cl`" (#184035)
Reverts llvm/llvm-project#183926 because of some BB failures.
[SLP]Do not consider condition with multiple uses and negate predicate as a candidate for inversed select
If the select/zext comparison has negate predicate and is used in
several places, it should not be considered as a candidate for inversed
zext/select pattern, it will be replaced by a negate vector predicate,
leading to an incorrect codegen for other uses
[clang-tidy][NFC] Don't call `getLangOpts` in `isLanguageVersionSupported` (#184029)
This is just a little inconsistency I noticed. Basically all checks
inspect the `LangOpts` parameter, but these two ignore the parameter and
call `getLangOpts` instead.
[ProfCheck] Exclude new GVN test
Added in a recent PR. We still have not gotten through GVN, so this is
likely caused by existing code. Exclude it to keep the bot green.
[LV] Handle sunk reverse VPInstruction in planContainsAdditionalSimps.
Licm can now sink reverse VPInstructions outside the loop region; they
won't be considered when computing costs. Account for that in
planContainsAdditionalSimplifications.
