[InstCombine] use logical-or matcher to avoid crash

This should prevent crashing for the example in issue #58552
by not matching a select-of-vectors-with-scalar-condition.

A similar change is likely needed for the related fold to
properly fix that kind of bug.

The test that shows a regression seems unlikely to occur
in real code.

This also picks up an optimization in the case where a real
(bitwise) logic op is used. We could already convert some
similar select ops to real logic via impliesPoison(), so
we don't see more diffs on commuted tests. Using commutative
matchers (when safe) might also handle one of the TODO tests.
