    M llvm/test/CodeGen/RISCV/condops.ll

  Log Message:
  -----------
  [RISC] Use hasBEXTILike in useInversedSetcc and shouldFoldSelectWithSingleBitTest. (#158366)

Add hasVendorXTHeadCondMov to shouldFoldSelectWithSingleBitTest.

The optimizations in these functions is equally applicable to these.

I changed the RUN line for xtheadcondmove in condops.ll to use XTHeadBs
to get coverage of the hasBEXTILike changes. I didn't think it was
worth an additional RUN line and check prefix.
