Evaluation

Test case has loop nest 128 levels deep. With new RPO parsing, the internal representation accurately represents the loop nest. Block frequency calculations go to infinity for some of the inner loops because of the limitations of the float representation.
Calculations in ifg_physical go to NaN and INF because of the high frequencies, which aren't accounted for in the asserts.
