[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.

pnpm: update to 12.0.0-rc.3
Pkgsrc changes:
* Use pre-release RC tag instead of release tag.
* One more patch for NetBSD support.
pnpm 12.0.0-rc.4 needs to wait for pkgsrc Rust updating to v1.97.1.
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.

converters/pecl-igbinary-session: New port: Replacement for the standard PHP serializer (+session support)
Igbinary is a drop in replacement for the standard PHP serializer.
Instead of time and space consuming textual representation, igbinary
stores PHP data structures in a compact binary form. Savings are
significant when using memcached or similar memory based storages for
serialized data.
This port supports sessions, a feature that is only available when the
session module is statically compiled into PHP. This port patch igbinary
to use the dynamically compiled session module.
