[X86] combineSelect - move vselect(cond, pshufb(x), pshufb(y)) -> or(pshufb(x), pshufb(y)) fold (#145475)
Move the OR(PSHUFB(),PSHUFB()) fold to reuse an existing
createShuffleMaskFromVSELECT result and ensure it is performed before
the combineX86ShufflesRecursively combine to prevent some hasOneUse
failures noticed in #133947 (combineX86ShufflesRecursively still
unnecessarily widens vectors in several locations).
