[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

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.

[Concepts] Correctly handle failure when checking concepts recursively
Based on discussion on the core reflector, it was made clear that a
concept that depends on itself should be a hard error, not a constraint
failure. This patch implements a stack of constraint-checks-in-progress
to make sure we quit, rather than hitting stack-exhaustion.
Note that we DO need to be careful to make sure we still check
constraints properly that are caused by a previous constraint, but not
derived from (such as when a check causes us to check special member
function generation), so we cannot use the existing logic to see if this
is being instantiated.
