[RISCV][GlobalISel] Add G_CLMULH support (#221686)
Add G_CLMULH to represent the high half of a carry-less multiplication
in generic Machine IR.
Translate llvm.riscv.clmulh to G_CLMULH and mark it legal for native
XLEN scalar types when Zbkc is available. Reuse the existing
SelectionDAG pattern to select the RISC-V CLMULH instruction.
[AMDGPU][lld] Remove "using namespace llvm" from AMDGPU.cpp (#222818)
AMDGPU class in anonymous namespace collides with llvm::AMDGPU, causing
an error with MSVC.
[CIR][AMDGPU] Add support for AMDGCN global/DS load builtins (#220611)
Adds codegen support for AMDGCN global and DS load/read builtins with
transpose variants. These builtins are lowered to their corresponding
`llvm.amdgcn.*` intrinsics.
[SSAF][PointerFlow] Factor out and make the pointer-flow matching reusable
The PointerFlowExtractor matches AST nodes representing pointer-flows
and converts them to entity-based data structures directly. This
commit divides this procedure into two steps: 1) match and represent
AST nodes as PointerFlowPairs; 2) convert PointerFlowPairs to
entity-based edges. Therefore, other SSAF tools may use
PointerFlowPairs.
The refactoring also improves coverage: it separates pointer-type
checking from structural matching, so structural matching alone now
discovers cases that were previously missed due to overly aggressive
type checking (e.g. a record-typed call argument or return value
initialized with a braced-init-list).
Along the way, this also fixes a bug for unnamed bit-fields.

[SSAF][PointerFlow] Drop unused TUSummaryExtractor param from translateDeclPointerLevel
TUSummaryExtractor is only needed to mint EntityIds when building an
EntityPointerLevel; translateDeclPointerLevel just walks the Expr and
returns raw DeclPointerLevels, so it never touched Extractor.
This is the second patch the radar below depends on:

NAS-143516 / 26.0.0 / rename the s3 service from truenas_s3 to s3 (by anodos325) (#19683)
service.query reported it as truenas_s3, the daemon's name rather than
the protocol's. The services_services row has to move with
ServiceInterface.name or nothing resolves it, so a migration renames it;
ServiceWriteRole is keyed by the name upper-cased and moves too.
Root is refused as an access key account and as a bucket owner. Both run
as uid 0, which no bucket grant and no file mode restrains.
The daemon's own messages get /var/log/truenas_s3.log, filtered on the
journal identifier it writes, s3d, and rotated the way scst and
truenas-discoveryd are. Its audit records are a separate path and are
untouched.
The systemd unit, the etc group and the tables keep the truenas_s3 name:
they are the daemon's, and nothing outside middleware names them.

correct dma_tag_lookup() loop
drm_cd.cd_ndevs[] has pointers to drm_softc not drm_device
Currently, dma_tag_lookup() is only used by the apldcp/apldrm drivers.
At the start of the softc for both of those is struct platform_device.
If the loop doesn't match the the function argument is cast to
struct platform_device *, so the problem was not noticed.
discussed with kettenis@ and apldcp/apldrm tested on m1 mac mini
[mlir][AMDGPU] Split the dialect declaration (NFC)
Introduce a self-contained dialect declaration so RegisterAllDialects does not
need the generated AMDGPU operation umbrella.
Across five controlled rebuilds of the affected TU, median instructions fell
from 71.757B to 70.331B (-1.987%) and median wall time fell from 11.01s to
10.77s (-2.180%).

[mlir][Func] Split the dialect declaration (NFC)
Introduce a self-contained dialect declaration and use it in ten configured
consumers that do not need the generated operation umbrella.
Across three controlled -j16 rebuilds of the affected TUs, median instructions
fell from 224.883B to 220.787B (-1.821%) and median wall time fell from 8.44s
to 8.31s (-1.540%).

[mlir][Bufferization] Split the dialect declaration (NFC)
Introduce a self-contained dialect declaration and use it in four consumers
that do not need the generated operation umbrella.
Across three controlled serial rebuilds of the affected TUs, median
instructions fell from 97.470B to 94.887B (-2.650%) and median wall time fell
from 15.20s to 14.70s (-3.289%). Three -j16 runs confirmed a 2.623% reduction
in instructions, with wall time improving 0.722% on the parallel critical path.
