David Sherwood df3d70b5a7 [Analysis] Add getPredicatedExitCount to ScalarEvolution (#105649) ...

Due to a reviewer request on PR #88385 I have created this patch
to add a getPredicatedExitCount function, which is similar to
getExitCount except that it uses the predicated backedge taken
information. With PR #88385 we will start to care about more
loops with multiple exits, and want the ability to query exit
counts for a particular exiting block. Such loops may require
predicates in order to be vectorised.

New tests added here:
