Jamie Schmeiser be1ff1fe58 [NFC] Refactor loop peeling code for calculating phi invariance. 
Summary:
Refactor loop peeling code by moving code for calculating phi invariance
into a separate class that does the calculation.  Redescribe and rework
the algorithm in preparation for adding increased functionality.  Add
test case that does not exhibit peeling that will be subsequently supported.
