NFC: MLIR Indexing Utils comment fix (#183438)

the comment for delinearize was incorrect and swapped modulus and
division, updated comment to match code

[flang-rt] Fix EXECUTE_COMMAND_LINE() on Windows (#184875)

Detect cmd.exe special status code 9009 that indicates "command not
found" condition. Crash the process if "command not found" detected when
CMDSTAT was not specified.

[lldb][Darwin] Don't try to insert breakpoint on corefiles (#184749)

lldb is printing an error that the kext-loaded notification breakpoint
can't be set when debugging a kernel corefile. The breakpoint only needs
to be inserted in live debug sessions.

[MLIR][XeGPU] Refactoring Transpose OP Layout Propagation (#184702)

This PR refactors Transpose Op Layout Propagation: 
1. Add inferTransposeSourceLayout() to layout utility, enhance layout
propagation and conflict handling to use this function
2. Add Layout utility: TransposeDims()
3. Refactor IsTransposeOf() and fix minor bugs
4. Fix minor issue in dropSgLayoutAndData()

[mlir][acc] Add Dialect Utils to OpenACCDialect deps (#184895)

[VPlan] Always process all argmin/argmax reductions in plan.

Follow-up to https://github.com/llvm/llvm-project/pull/170223.
Instead of exiting early, continue processing remaining reductions in
the loop. This ensures all multi-use reductions are properly converted
or the plan is rejected if there are unconvertable patterns.

Fixes https://github.com/llvm/llvm-project/issues/184729.

[lldb] Fix bytecode.test (#184903)

Follow up to #184714.

There are some other latent bugs here inside the formatter, but for now
this puts the test in a working state.

[flang] Reject PARAMETER constants in NAMELIST groups (#178960)

The Fortran standard does not allow `PARAMETERS` within a
`namelist-group-object`, it should only allow variables. An error should
be emitted when a `PARAMETER` is found within a `namelist-group-object`.

Fixes: #178955

[libc][math] Optimize `asinpif` and `acospif` using estrin's scheme (#184286)

Optimize `asinpif` and `acospif` using [Estrin's
scheme](https://en.wikipedia.org/wiki/Estrin%27s_scheme).

## Benchmarking in **debug mode**
### **before**
**asinpif**

```
Ntrial = 40 ; Min = 0.000 + 350.920 clc/call; Median-Min = 450.477 clc/call; Max = 468.882 clc/call;
```

**acospif**
```
Ntrial = 40 ; Min = 0.000 + 309.248 clc/call; Median-Min = 384.386 clc/call; Max = 420.073 clc/call;
```

[CIR][AArch64] Add missing lowerings for vceqz_* Neon builtins (#184893)

Implement the remaining CIR lowerings for the AdvSIMD (Neon)
`vceqz{|q|d|s}_*` intrinsic group (bitwise equal to zero).

The `vceqzd_s64` variant was already supported; this patch completes
the rest of the group [1].

Tests for these intrinsics are moved from:
  * test/CodeGen/AArch64/neon-misc.c
  
to:
  * test/CodeGen/AArch64/neon/intrinsics.c

The implementation largely mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp.

`emitCommonNeonBuiltinExpr` is introduced to support these lowerings.
`getNeonType` is moved without functional changes.

libclc: Define work_group_barrier

Previously only the old barrier name was implemented. Define this
as an indirection around the new name, and move it to common code.
The target implementations are already provided by __clc_work_group_barrier,
so targets were unnecessarily duplicating these.

This also fixes the default scope, which should be
memory_work_group_scope. Previously this was guessing that
if the flags included global memory, it makes the scope
device which is not the case.

[LoopFusion] Correction in the comments (NFC) (#184689)

The comments in the code should have been updated following the change
in https://github.com/llvm/llvm-project/pull/183353. This PR addresses
that issue.

[docs] Add exception to AI tool policy for Bazel build fixer (#183408)

The Bazel RFC concluded earlier this month:
https://discourse.llvm.org/t/rfc-ai-assisted-bazel-fixer-bot/89178/93

I felt the best way to document this decision was to incorporate it into
this policy document.

[flang][OpenMP] Implement utility to locate OmpClause in ODS, NFC (#184866)

Simplify looking for a specific clause in OmpDirectiveSpecification.
This is alternative to DirectiveStructureChecker::FindClause for when
the internal checker structures have not yet been updated in the AST
traversal.

[ssaf][UnsafeBufferUsage] Add support for extracting unsafe pointers from all kinds of contributors

- Generalize the -Wunsafe-buffer-usage API for finding unsafe pointers in all kinds of Decls
- Add support in SSAF-based UnsafeBufferUsage analysis for extracting from various contributors
- Mock implementation of HandleTranslationUnit

[flang][openacc] Relax semantic check on cache directive (#184887)

The specification doesn't really forbid the colon notation to be used to
specify the full array. Reference compiler accepts this and our lowering
can already handle it.

[AMDGPU] add back the true16 pattern for cvt_pk_rtz (#184857)

I found that the `SupportedRoundMode` pattern for true16 mode is removed
in https://github.com/llvm/llvm-project/pull/177069 by mistake. Added it
back in this patch and add gfx11 to the test which runs true16 mode
