This revision introduces a utility to hoist affine.if operations past
surrounding affine.for/parallel operations. The hoisting works for both
perfect/imperfect nests and in the presence of else blocks. The hoisting
is currently to as outermost a level as possible. Uses a test pass to
test the utility. Add convenience method Operation::getParentWithTrait<Trait>.

Depends on D77487 <https://reviews.llvm.org/D77487>.
