Recognize XOR-based periodic induction. Rationale: This is a commonly used construct (e.g. x = !x for booleans and x ^= 1 for integers). This CL prepares some upcoming optimizations that exploit such inductions. Change-Id: I46edffb9de1075a836995daf5c2dfff7891f3034 Test: 530-checker-loops2 and induction_var_analysis_test
