[Object] Remove unused argument of DataExtractor constructor (NFC) (#197124)

`AddressSize` parameter is not used by `DataExtractor` and will be
removed in the future. See #190519 for more context.

[ExpandIRInsts] Drop ProfcheckDisableMetadataFixes in some cases (#200627)

This is unnecessary inside of applyProfMetadataIfEnabled because it is
already handled before the callback lambda gets called within the
function. There was also a redundant case to remove.

[bazel] Add CLANG_USE_EXPERIMENTAL_CONST_INTERP (fixup for #199396) (#200619)

[IR] Fix !invariant.group in combineMetadataForCSE when K moves (#200551)

SimplifyCFG mergeConditionalStoreToAddress currently transforms

    if (cond)
      store ptr, x !invariant.group;
    else
      store ptr, y;

into

    store ptr, select(cond, x, y) !invariant.group;  // BUG

It's clearly not valid to preserve !invariant.group here.

Fix this inside combineMetadataForCSE.  It can only preserve
!invariant.group if

 1. !DoesKMove, meaning that original instruction ("K") is replaced by

[asan] NFC: clang-format allocator-related files (#200478)

Depends on #200615
Groundwork for #196413.

Mechanical cleanup of allocator related files in preparation of
functional changes. clang-format (v21.1.2) applied whole-file to:

  compiler-rt/lib/asan/asan_allocator.cpp
  compiler-rt/lib/asan/asan_allocator.h
  compiler-rt/lib/asan/asan_malloc_linux.cpp
  compiler-rt/lib/asan/asan_malloc_mac.cpp
  compiler-rt/lib/asan/asan_new_delete.cpp
  compiler-rt/lib/asan/tests/asan_noinst_test.cpp

Both compiler-rt/lib/asan/.clang-format and
compiler-rt/lib/sanitizer_common/.clang-format use
"BasedOnStyle: Google", so pointer alignment becomes "Type* name"
throughout.

[asan] NFC: tag ambiguous literal args at Allocate call sites (#200615)

Groundwork for #200478

Add /*name=*/ comments to ambiguous literal call-site arguments in
compiler-rt/lib/asan/asan_allocator.cpp so the parameter name is visible
at the call site for the Allocate / instance.Allocate uses. Covers the
can_fill flag and the bare alignment literals (8, 16, 0) used by:

  asan_malloc / asan_vec_malloc / asan_realloc / asan_valloc /
  asan_pvalloc / asan_memalign / asan_aligned_alloc /
  asan_posix_memalign / asan_new / asan_new_aligned

and the internal Reallocate / Calloc paths.

NFC.

[IRBuilder] ConstFold unary intrinsics (#200496)

Extend TargetFolder and InstSimplifyFolder to fold unary intrinsics.
CreateUnaryIntrinsic now returns a Value, similar to
CreateBinaryIntrinsic, and this has necessitated more changes.

[VPlan] Factor vputils::getIntrinsicID (NFC) (#200174)

In preparation to get getOpcodeOrIntrinsicID used by CSE to handle calls
and to constant-fold intrinsic calls, factor out vputils::getIntrinsicID
from VPlanPatternMatch to re-use.

[clang-tidy] `use-ranges`: preserve used unique results

Preserve iterator uses when replacing std::unique with std::ranges::unique by appending .begin() in used-result contexts.

Fix #127658

Assisted by Codex.

[clang-tidy] `use-ranges`: avoid unsafe result fix-its

Preserve callable results with .fun, allow structured-binding-safe rewrites, and keep diagnostics while suppressing unsafe fix-its when ranges result objects do not match the original result shape.

Assisted by Codex.

[clang-tidy] `use-ranges`: preserve remove iterator results

Preserve used iterator results for remove, partition, stable_partition, and rotate-style replacements by appending .begin() where the ranges algorithm returns a subrange.

Fix #124794

Assisted by Codex.

[clang-tidy] `use-ranges`: preserve output results

Preserve used output iterator results for output algorithm replacements by appending .out where the ranges algorithm returns an algorithm result object.

Fix #110223
