Refine movhfcc.

For AVX512-FP16, HFmode only supports vcmpsh whose dest is mask
register, so for movhfcc, it's

vcmpsh op2, op1, %k1
vmovsh op1, op2{%k1}
mov op2, dest

we only have mask comparison for HFmode, ix86_expand_fp_movcc needed to be
updated for it.

The testcase is rejected in GCC 11, so not a regression.
