IR printing improvement for loop passes
Summary:
Loop-pass printing is somewhat deficient since it does not provide the
context around the loop (e.g. preheader). This context information becomes
pretty essential when analyzing transformations that move stuff out of the loop.
Extending printLoop to cover preheader and exit blocks (if any).
