[Attributor]Detect SCCs with unbounded cycles

This patch implements containsUnboundedCycle which checks for unbounded cycle
which is either a loop that does not have a maximal trip count or any other
cycle.

It contains some fixes for willreturn tests and addition of bounded
and unbounded loop tests.
