[PATCH] D62341: [DAGCombine][X86][AArch64][AMDGPU][MIPS][PPC] (sub x, c) -> (add x, -c) vector edition.

[Simon Atanasyan via Phabricator via llvm-commits]

I do not think it's good for MIPS because this patch replace one `subvi` instruction by pair of `ldi` and `addv`. Are you going to fix such regressions?
