[clang][bytecode] Fix assertion failure in in valid continue stmt (#216547)
We need to handle the missing TargetLabel here, similarly to what we do
in break statements.
[MLIR][LLVM] Preserve pointer-valued metadata operands on import (#215743)
convertMetadataToAttrImpl only modelled ConstantInt operands wrapped in
a ConstantAsMetadata, so any metadata node containing a pointer constant
could not be represented and the whole node was rejected.
Add #llvm.md_null and #llvm.md_addrspacecast to model
ConstantPointerNull and addrspacecast constant expressions, keeping the
address space so that `ptr null` and `ptr addrspace(1) null` stay
distinct. MDAddrSpaceCastAttr verifies that its operand is itself
pointer-valued metadata.
Global values are constants, so ValueAsMetadata::get wraps them in a
ConstantAsMetadata and they never reached the ValueAsMetadata case.
Match them in the ConstantAsMetadata case instead, which also
generalizes the existing function-only handling to any named global
value and makes the addrspacecast operand representable.
Mirror both attributes in ModuleTranslation::convertMetadataAttr so the

misc/xdelta3: Update to 3.2.0 and take maintainership
Port changes:
- Switch the upstream build from Autotools to CMake
(see https://github.com/jmacd/xdelta)
- Update the declared license from GPLv2+ to Apache 2.0
(as per https://github.com/jmacd/xdelta)
- Enable armor support and the static-library build
- Install the public header, static library, pkg-config file, and CMake
package metadata
- Remove the obsolete regtest patch (not required anymore due to
changes to the build infrastructure)
- Update WWW, COMMENT, and pkg-descr to reflect these chagnes
- Add a complete pkg-plist

[InstCombine] Fold shl of constant by cttz into multiply of lowest set bit (#214517)
Currently, `C << cttz(X, true)` generates a DeBruijn lookup table on
RV64I (13 instructions).
And this patch adds a fold in InstCombine:
`C << cttz(X, true) --> (-X & X) * C`
This reduces the instruction count from 13 to 3 on RV64I.
The fold requires that cttz has a single use (to avoid increasing
instruction count)

clang/AMDGPU: Stop passing redundant -target-cpu to cc1
Now that the exact target is encoded in the triple's subarch field,
-target-cpu is redundant. This avoids polluting the resultant IR with
unwanted "target-cpu" attributes. The net result is the desired codegen
when compiling libraries for a major subarch and linking it into a
program compiled for a specific arch. e.g., compiling for "gfx9-generic"
would pollute the IR with "target-cpu"="gfx9-generic", so codegen
would ultimately be performed for the generic target even after
linking into the concrete gfx9 cpu. The specialization will now be
achieved by merging the triples without the linker or optimization
passes needing to fixup function attributes.
AMDGPU: Start using subarch in attributor instead of subtarget
Avoid querying the subtarget for functions when the relevant
properties are known from the triple. The various subtarget
group size functions should also be decoupled from the subtarget,
but those are trickier to untangle.

clang: Start using new amdgpu subarch triples
Fixup invocations using --target=amdgcn + -mcpu to introduce
the subarch in the triple.
For offload toolchains, a single toolchain is constructed for the
top level amdgpu architecture, and the effective triple is used for
target specific tool invocations.
The specifics of the resource directory layout are tbd. This does
try to find resources in the subarch named directory. The paths
are searched at toolchain creation time, so that does not work
when there are multiple subarches.

AArch64: Use MIPatternMatch in PostLegalizerCombiner ext checks (#216512)
Replace the getVRegDef + opcode-check idiom with mi_match. Add an
m_GSExtInReg matcher for G_SEXT_INREG, which has an extra immediate
operand and so does not fit the plain unary-op matcher shape.
