[PATCH] i386: Combine the FADD(A, FMA(B, C, 0)) to FMA(B, C, A) and combine FADD(A, FMUL(B, C)) to FMA(B, C, A).

Hi, This patch is to support transform in fast-math something like _mm512_add_ph(x1, _mm512_fmadd_pch(a, b, _mm512_setzero_ph())) to _mm512_fmadd_pch(a, b, x1). And support transform _mm512_add_ph(x1, _mm512_fmul_pch(a, b)) to _mm512_fmadd_pch(a, b, x1). Ok for master? gcc/ChangeLog:
