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).

; This test checks -print-after/before on loop passes
; Besides of the loop itself it should be dumping loop pre-header and exits.
