[PATCH] D33001: [RuntimeUnrolling] Add logic for loops with multiple exit blocks

[Anna Thomas via Phabricator via llvm-commits]

Addressed review comments. Now we no longer clone the loop exits, but generate the edges to the original loop exits
and canonicalize to dedicated loop exits afterwards.
This automatically helps support other loop exits having successors, so that restriction is removed.
Added one more test case to verify exits having successors.
