[x86] try harder to scalarize a vector load with extracted integer op uses
extract_vec_elt (load X), C --> scalar load (X+C)
As noted in the comment, DAGCombiner has this fold -- and the code in this
patch is adapted from DAGCombiner::scalarizeExtractedVectorLoad() -- but
x86 should benefit even if the loaded vector has other uses as long as we
apply some other x86-specific conditions. The motivating example from #50310
is shown in vec_int_to_fp.ll.
Fixes #50310
