[PATCH] D153544: [AMDGPU] Use V_FMA_MIX* more often

[Mateja Marjanovic via Phabricator via llvm-commits]

matejam added a comment.

@arsenm Would it be correct if I wrote a pattern in MadFmaMixPats multiclass, that finds (f16 (fptrunc (f32 (fmul %src1, %src2)))) and turns it into v_fma_mixlo_f16 %src1, %src2, 0.
The add would stay the same.
