  -----------
  [clang][AArch64] Use .i16.f16 intrinsic formats for vcvth*_[s|u]16_f16 (#156029)

Use .i16.f16 intrinsic formats for intrinsics like vcvth_s16_f16.
Avoids issues with incorrect saturation that arise when using .i32.f16
formats for the same conversions.
Fixes https://github.com/llvm/llvm-project/issues/154343.
