Fold _mm{,256,512}_abs_{epi8,epi16,epi32,epi64} into gimple ABS_EXPR.

Also for 64-bit vector abs intrinsics _mm_abs_{pi8,pi16,pi32}.

Yes, let me do the folding.
FYI, for those floating point abs intrinsics, they're already implemented as 

_mm512_abs_ps (__m512 __A)
{
  return (__m512) _mm512_and_epi32 ((__m512i) __A,
_mm512_set1_epi32 (0x7fff));
}

And no need for folding.
