[lldb] Fix abi_tag parsing for operator<< and operator-named tags (#170224)
The parser now correctly handles:
- abi_tags attached to operator<<: `operator<<[abi:SOMETAG]`
- abi_tags with "operator" as the tag name: `func[abi:operator]`
[OpenCL][NVPTX] Don't set calling convention for OpenCL kernel (#170170)
Fixes #154772
We previously set `ptx_kernel` for all kernels. But it's incorrect to
add `ptx_kernel` to the stub version of kernel introduced in #115821.
This patch copies the workaround of AMDGPU.
[LowerMemIntrinsics] Optimize memset lowering
This patch changes the memset lowering to match the optimized memcpy lowering.
The memset lowering now queries TTI.getMemcpyLoopLoweringType for a preferred
memory access type. If that type is larger than a byte, the memset is lowered
into two loops: a main loop that stores a sufficiently wide vector splat of the
SetValue with the preferred memory access type and a residual loop that covers
the remaining bytes individually. If the memset size is statically known, the
residual loop is replaced by a sequence of stores.
This improves memset performance on gfx1030 (AMDGPU) in microbenchmarks by
around 7-20x.
I'm planning similar treatment for memset.pattern as a follow-up PR.
For SWDEV-543208.

[CodeGen] Add MO_LaneMask type and a new COPY_LANEMASK instruction (#151944)
Introduce MO_LaneMask as new machine operand type. This can be used to
hold liveness infomation at sub-register granularity for register-type
operands. We also introduce a new COPY_LANEMASK instruction that uses
MO_lanemask operand to perform partial copy from source register
opernad.
One such use case of MO_LaneMask can be seen in #151123, where it can be
used to store live regUnits information corresponding to the source
register of the COPY instructions, later can be used during CopyPhysReg
expansion.
[Hexagon][NFC] Drop no-op getMaskedMemoryOpCost/getGatherScatterOpCost stubs (#170426)
These stubs (from 4bdf1aa416b02) don’t actually override anything.
Removing them eliminates the need for a local getMemIntrinsicCost()
forwarder in #169885.
[clang] Propagate definition data to all redecls (#170090)
Fix the propagation added in commit 0d490ae55f to include all redecls,
not only previous ones. This fixes another instance of the assertion
"Cannot get layout of forward declarations" in getASTRecordLayout().
Kudos to Alexander Kornienko for providing an initial version of the
reproducer that I further simplified.
Fixes #170084
unbound: overview: fix quick allow/blocklist actions
The quick fix here is to block & allow on every defined policy. Ideally
one should be able to select a policy where an entry should apply
to in the case of a block action, and map back to the policy in case
of an allow action. The latter isn't possible in the current construct
yet as it needs a slight adjustment to the data format.

Move CodeGenFunction::EmitScalarOrConstFoldImmArg; NFC (#170286)
This function is called from various .cpp files under `TargetBuiltins/`,
and was moved unintentionally into `AMDGPU.cpp` in PR #132252. Move it
to a common place.
