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

[Roman Lebedev via Phabricator via llvm-commits]

@hfinkel should i be worried about PPC regressions here?
Those are there regardless of the patch (instcombine already did this fold).
I'm not yet sure how to handle them, in some of these patterns the constant
is already constant-pool load, in some cases it's bitcasted, etc.
