[PATCH] D75889: AMDGPU: Use V_MAC_F32 for fmad.ftz

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

It was used in the div expansion for some non obvious reason. As far as I know it means 0.0 * x = 0.0, but I am not sure it is needed in this case.
Please run PSDB on this change, if it passes then LGTM.
