JDK-8346552 - C2: Add IR tests to check that Parse Predicate cloning in Loop Unswitching works as expected
Description
Most major compiler phases like parsing and matching print a "BEFORE_MAJOR_PHASE" and "AFTER_MAJOR_PHASE". Loop optimizations --- also a major phase, I would argue --- do not. Printing "BEFORE_LOOP_OPTS" and "AFTER_LOOP_OPTS" would be useful for inspecting the ideal graph in the IGV and matching the ideal graph in the IR-framework.
