[X86] combineEXTEND_VECTOR_INREG - don't attempt to shuffle combine ANY_EXTEND_VECTOR_INREG without SSE41
Without SSE41, ANY_EXTEND_VECTOR_INREG nodes are likely to be prematurely combined to a target shuffle preventing generic sign extension folds.
Fixes a number of sign-extend regressions in D127115.
