Roman Lebedev 7beb057809 [MIPS] For vectors, select add %x, C as sub %x, -C if it results in inline immediate

Summary:
As discussed in https://reviews.llvm.org/D62341#1515637,
for MIPS `add %x, -1` isn't optimal. Unlike X86 there
are no fastpaths to matearialize such `-1`/`1` vector constants,
and `sub %x, 1` results in better codegen,
so undo canonicalization
