[lldb/DWARF] Always construct a DWARFDebugInfo object

Change the return value of SymbolFileDWARF::DebugInfo from a pointer to
a reference, and remove all null checks.

Previously, we were not constructing the DebugInfo object when the
debug_info section was empty. Now we always construct the object but
it will return an empty list of dwarf units (a thing which it already
supported).

[compiler-rt] [builtins] Fix logb / logbl tests

Like was done before in D67999 for `logbf`, this patch fixes the tests for
the internal compiler-rt implementations of `logb` and `logbl` to consider
all NaNs equivalent. Not doing so was resulting in test failures for
riscv64, since the the NaNs had different signs, but the spec doesn't
specify the NaN signedness or payload.

Fixes bug 44244.

[NFC] Remove ar/ranlib test noise during cmake step

At least on RHEL, ar outputs on stderr a message similar to

        .../bin/ar: creating t.a

Which creates noise during the cmake step. Get rid of it.

[ARM,MVE] Add vqdmull[b,t]q intrinsic families

Summary:
This patch adds two families of ACLE intrinsics: vqdmullbq and
vqdmulltq (including vector-vector and vector-scalar variants) and the
corresponding LLVM IR intrinsics llvm.arm.mve.vqdmull and
llvm.arm.mve.vqdmull.predicated.

[clang-tidy] misc-no-recursion: point to the function defs, not decls

Results in slightly better UX.
This actually was the initial intent, but it kinda got lost along the way.

SpeculativeExecution: fixed ingoring free execution

Summary:
After updating cost model in AMDGPU target (47a5c36b37f0) the pass started to
ignore some BBs since they got all instructions estimated as free.

[AMDGPU] simplifyI24 - replace GetDemandedBits with SimplifyMultipleUseDemandedBits

GetDemandedBits mostly just calls SimplifyMultipleUseDemandedBits now, but it does a very blunt constant simplification that SimplifyMultipleUseDemandedBits avoids.

If we need to demand bits from constants we should handle this through ShrinkDemandedConstant/targetShrinkDemandedConstant.

@arsenm confirmed that the sign extended immediates are better for code size.
