[LV] Use IVUpdateMayOverflow to set HasNUW. (#111758 )

If IVUpdateMayOverflow is false, we proved that the induction increment
cannot overflow in the vector loop. This allows setting NUW in some
cases when folding the tail.

[LV] Handle SwitchInst in ::isPredicatedInst.

After f0df4fbd0c7b, isPredicatedInst needs to handle SwitchInst as well.
Handle it the same as BranchInst.

This fixes a crash in the newly added test and improves the results for
one of the existing tests in predicate-switch.ll

Should fix https://lab.llvm.org/buildbot/#/builders/113/builds/2099.
