Sanjay Patel 72ba2489f2 [PatternMatch] don't match a scalar select of bool vectors as a logical-and or logical-or ...

Most folds based on these matchers already check to make sure the
condition type is the same as the select type, and it seems unlikely
that a fold would want to handle a scalar-select-of-vectors pattern
(there are no regression tests for it).

This is a preliminary step for fixing #issue 58552. The fold(s)
responsible for that crash (D101807, D101375) don't use the matchers
yet, but they probably should.
