xfail are added for testcases related to truncmn2/extendmn2 expanders since V2HF/V4HFmode
are not supported yet, they should be removed later.

  Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
  Newly added runtime testcases passed on sde{-m32,}.

Hongyu Wang (5):
  AVX512FP16: Add expander for smin/maxhf3.
  AVX512FP16: Add fix(uns)?_truncmn2 for HF scalar and vector modes
  AVX512FP16: Add float(uns)?mn2 expander
  AVX512FP16: add truncmn2/extendmn2 expanders
  AVX512FP16: Enable vec_cmpmn/vcondmn expanders for HF modes.

liuhongt (2):
  AVX512FP16: Add expander for rint/nearbyinthf2.
  AVX512FP16: Add expander for fmahf4
