r256763 had promoteLoopAccessesToScalars check for the existence of a
catchswitch when the exit blocks were populated but
promoteLoopAccessesToScalars may be called with a prepopulated set of
exit blocks which would also need to be checked.
This fixes PR26019.

Inserting after a catchswitch results in verifier errors, bail out on

We had two bugs here:
- We might try to sink into a catchswitch, causing verifier failures.
- We will succeed in sinking into a cleanuppad but we didn't update the
funclet operand bundle.
