[X86] LowerCLMUL - improve vXi32 codegen (#221289)
Shuffle combining is struggling to handle the mixture of vector
unrolling, truncations and optimal use of PCLMULQDQ swizzles, this patch
gives us more optimal lowering direct instead of relying on fixup.
Use the PCLMULQDQ lo/hi control immediate to handle anyext i64 element
evaluation - along with shifting the upper elements down to the lowest
bits of the i64 in parallel
Use UNPACK build vector pattern to avoid FPR<->GPR traffic
CLMULH needs to be handled in a future patch, and vXi16 /might/ be worth
handling as well.
sysutils/f3: Update 8.0 => 10.0, take maintainership
Upstream moved sources to src/, build output to build/, the man page to
man/ and the helper scripts to scripts/, adapt do-install accordingly.
While here, switch to DISTVERSION and pet portclippy.

[Clang] Fix Crash in Sema::DiagnoseUnguardedAvailability On 'if' With No Condition (#220004)
**Problem**
C++ 23 introduced consteval expressions which allows `if` statements to
have no condition:
```
if consteval {
}
```
`DiagnoseUnguardedAvailability::TraverseIfStmt` Assumed `If->getCond()`
would never return a `nullptr`, causing a `nullptr` dereference.
Fixes #219948
CodeGen: Move frame-pointer queries out of TargetOptions (#221416)
These used to depend on a TargetOptions field, which was removed
at some point. These are now only depend on MachineFunction,
so move the attribute check there.

bhyve: Do not panic on invalid input in HDA emulation
The emulated HDA controller passed values taken from guest registers and
from guest memory straight into assert(), so a guest could abort bhyve
with values the emulation did not expect. Reject them instead.
In case the guest asked to start something and it failed, clear the
corresponding run/enable bit.

DAGCombiner: Drop AllowFPOpFusion from visitFADDForFMACombine
Rewrites fp-dp3.ll to use flags on individual patterns. It weirdly
used different triples for the fp-contract on and off cases, seemingly
an artifact of the ARM64 and AArch64 merge.

[SLP]Fix crash on extractelement with undef/poison index in getEntryCost
canReuseExtract treats undef/poison-index extracts as holes, so such
extracts can end up in a vectorized ExtractElement entry. The cost
model dereferenced getExtractIndex() unconditionally, causing a crash.

clang: Distinguish unspecified from disabled exception model
Add ExceptionHandlingKind::Default so clang can tell an unspecified
exception model from an explicit -exception-model=none.
