[MLIR][ODS] Make dialect attribute helper member functions const (NFC) (#181111)
This commit marks member functions of dialect attribute helpers as
constant. This ensures that these helpers can be used as members of
rewrite patterns, whose `matchAndRewrite` functions are marked as const
as well.

[lldb] Fix LLDB header guards (NFC) (#181312)
Fix LLDB header guards using clang-tidy's llvm-header-guard check. A
bunch of headers have been moved or renamed and we often forget to
update the header guard.
[ELF] Add target-specific relocation scanning for x86 (#178846)
Implement scanSection/scanSectionImpl for i386 and x86-64 to
* enable devirtualization of getRelExpr calls
* eliminate abstraction overhead for PLT-to-PCRel optimization, TLS
relocations
* optimize for R_X86_64_PC32 and R_X86_64_PLT32: they consist of 95%
relocations in `lld/ELF/**/*.o` files.
* enable future optimization to remove `loc` from `getRelExpr` (only
used by X86.cpp `R_386_GOT32[X]`)
at the cost of more boilerplate.
TLS relocation handling is inlined into scanSectionImpl. Also,
- Remove getTlsGdRelaxSkip
- Replace TLS-optimization-specific expressions:
- R_RELAX_TLS_GD_TO_LE, R_RELAX_TLS_LD_TO_LE, R_RELAX_TLS_IE_TO_LE →

[RISCV] Remove RISCVISD::WMACC*. Match during isel. NFC (#181197)
I think we may want to be able to fold ADDD nodes independent of the MUL
in some cases. For example turning NSRAI into NSRARI.
If we fold ADDD into WMACC we would need to be able to extract it again.
Keep the nodes separate avoids this.
Code change was assisted by AI.
[IndVarSimplify] Add safety check for getTruncateExpr in genLoopLimit (#181296)
getTruncateExpr may not always return a SCEVAddRecExpr when truncating
loop bounds. Add a check to verify the result type before casting, and
bail out of the transformation if the cast would be invalid.
This prevents potential crashes from invalid casts when dealing with
complex loop bounds.

[MLIR][XeGPU][TransformOps] set_op_layout_attr supports setting anchor layout (#172542)
Changes `transform.xegpu.set_op_layout_attr` to support xegpu anchor
layouts. By default, if `result` and `operand` bool arguments are unset,
this transform op sets the op's anchor layout, if the op supports it
(otherwise emits a silenceable failure).
In contrast to the earlier implementation, setting the operand layout
now requires setting the new `operand` argument.
nvmm(4): Extract out nvmm_x86_internal.h from nvmm_x86.h
Similar to nvmm_internal.h, extract the kernel-only bits from nvmm_x86.h
and put into a separate 'nvmm_x86_internal.h'.
