  Log Message:
  -----------
  [clang] Lower non-builtin sincos[f|l] calls to llvm.sincos.* when -fno-math-errno is set (#121763)

This will allow vectorizing these calls (after a few more patches). This
should not change the codegen for targets that enable the use of AA
during the codegen (in `TargetSubtargetInfo::useAA()`). This includes
targets such as AArch64. This notably does not include x86 but can be
worked around by passing `-mllvm -combiner-global-alias-analysis=true`
to clang.

Follow up to #114086.
