Max Kazantsev 63a8861896 [IRCE] Fix SCEVExpander's usage in IRCE ...

When expanding exit conditions for pre- and postloops, we may end up expanding a
recurrency from the loop to in its loop's preheader. This produces incorrect IR.

This patch ensures that IRCE uses SCEVExpander correctly and only expands code which
is safe to expand in this particular location.
