Support vec_fmaddsub/vec_fmsubadd for vector HFmode.
AVX512FP16 supports vfmaddsubXXXph and vfmsubaddXXXph.
Also remove scalar mode from fmaddsub/fmsubadd pattern since there's
no scalar instruction for that.
gcc/ChangeLog:
PR target/81904
* config/i386/sse.md (vec_fmaddsub<mode>4): Extend to vector
HFmode, use mode iterator VFH instead.
(vec_fmsubadd<mode>4): Ditto.
(<sd_mask_codefor>fma_fmaddsub_<mode><sd_maskz_name><round_name>):
Remove scalar mode from iterator, use VFH_AVX512VL instead.
(<sd_mask_codefor>fma_fmsubadd_<mode><sd_maskz_name><round_name>):
Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr81904.c: New test.
