  Log Message:
  -----------
  [AArch64] Add some basic handling for bf16 constants.

This adds some basic handling for bf16 constants, attempting to treat them a
lot like fp16 constants where it can. Zero immediates get lowered to FMOVH0,
others either get lowered to FMOVWHr(MOVi32imm) or use FMOVHi if they can.
Without fp16 they get expanded. This may not always be optimal, but fixes a gap
in our lowering. See llvm/test/CodeGen/AArch64/f16-imm.ll for the equivalent
fp16 test.

  Log Message:
  -----------
  [RISCV] Use correct LMUL!=1 types for __attribute__((riscv_rvv_vector_bits(N)))

We used to convert them to M1 types in arguments and return
value, which causes failures in CodeGen since it is not legal
to insert subvectors with LMUL>1 to M1 vectors.

Fixes 64266
