Ana Pazos 8821a9ef6b [AArch64 NEON] Fixed fused multiply negate add/sub patterns 
The correct pattern matching should be:

- fnmadd is (-Ra) + (-Rn)*Rm  which should be matched as:

  fma (fneg node:$Rn),  node:$Rm, (fneg node:$Ra) and as

  (f32 (fsub (f32 (fneg FPR32:$Ra)), (f32 (fmul FPR32:$Rn, FPR32:$Rm))))

- fnmsub is (-Ra) + Rn*Rm which should be matched as

  fma node:$Rn,  node:$Rm, (fneg node:$Ra) and as

  (f32 (fsub (f32 (fmul FPR32:$Rn, FPR32:$Rm)), FPR32:$Ra))))
