[DAGCombiner] match inverted/swapped patterns for vselect of mask of signbit
This was noted as a follow-up to D113212 / D113426:
4fc1fc4005f7

The canonicalization rules for these IR patterns are complicated,
and we were not matching the expected forms in 2 out of the 3
cases. We can make codegen more robust by matching the swapped
forms (and that will also work if these patterns are created late).
