[Clang] Do not try to create invalid variable specializations. (#190960)
When a variable specialization is ambiguous,
we would still create a node for it.
If the first such specialization takes places in a sfinae context, ie
when appearing in a concept, the initial diagnostic was silence, but no
further errors were emitted on that specialization as the variable was
created anyway.
Instead we do not create a specialization in this case.

[AArch64] Fix broken SME code with GlobalISel (#191140)
The checks introduced in #190135 are too restrictive because no SVE or
SME is required to compile streaming-compatible or agnostic-ZA
functions. Now it generates incorrect code for
streaming-compatible/agnostic-ZA functions when the function has no
`+sve` or `+sme`.
nut tweaks:
fix nutclient manpages and start installing them (files contained just .So
links, so replace with symlinks)
install missing html files
some other minor cleanup
[NFC][SPIR-V] Remove unnecessary 'REQUIRES: asserts' from tests (#190986)
Remove `REQUIRES: asserts` from tests that don't use any assertions-only
functionality and should run for all build configurations
tests: Add retry loop for VEEAM alert
This commit adds a retry loop to a function that's used to
validate VEEAM alert behavior due to periodic test failures
caused by timing of a background alert processing task during
test runs.
[LV] Update forced epilogue VF options to allow different VFs than main. (#190393)
Previously, forced epilogue vector factors via the command line options
required to match the forced main VF (or the VF to be built in general).
This leads to a number of akward tests, where we end up with dead
epilogue vector loops.
Update the logic to build an additional VPlan with the epilogue vector
factor, and require the provided epilogue VF to be < IC * MainLoopVF.
Otherwise, epilogue vectorization is skipped.
This only impacts the forced epilogue VF option used for testing and
ensures epilogue tests to cover more realistic scenarios and make them
more robust w.r.t. to additional VPlan-based folding.

[DAG] computeKnownFPClass - Add handling for AssertNoFPClass (#190185)
Resolves #189478
Adds code to handle AssertNoFPClass in computeKnownFPClass and adds IR
test coverage for RISC-V.
[Clang] Do not create a NoSFINAETrap for variable specialization. (#191000)
There is no thing in the standard that says this should happen outside
of the immediate context.

[AMDGPU] Use wavefront scope for single-wave workgroup synchronization (#187673)
Workgroup-scoped fences and non-relaxed workgroup atomics were
previously legalized with synchronization strong enough for multi-wave
workgroups.
When the kernel's maximum flat work-group size does not exceed the
wavefront size, the workgroup contains only a single wavefront, so
workgroup-scoped synchronization is equivalent to wavefront scope and
the stronger legalization is unnecessary.
SIMemoryLegalizer now demotes workgroup scope to wavefront scope
in this case for workgroup-scoped fences and for non-relaxed atomic
load, store, atomicrmw, and cmpxchg operations.
This allows subsequent legalization to operate at wavefront scope.
The decision is based on AMDGPUSubtarget::isSingleWavefrontWorkgroup.
