[PATCH] D80429: [NFC][PowerPC] Remove unused node PPCISD::VMADDFP and PPCISD::VNMSUBFP

[Qiu Chaofan via Phabricator via llvm-commits]

Thanks for doing this. Actually, we can't generate `vnmsubfp` for expected pattern now, since `fneg` is illegal for `v4f32` type: `(set v4f32:$vD, (fneg (fma v4f32:$vA, v4f32:$vC, (fneg v4f32:$vB))))`. We should be able to handle this after D76585 <https://reviews.llvm.org/D76585> landed.
