XRay allows tuning by minimum function size, but also always instruments functions with loops in them. If the minimum function size is set to a large value the loop instrumention ends up causing most functions to be instrumented anyway. This adds a new flag, -fxray-ignore-loops, to disable the loop detection logic. Differential Revision: https://reviews.llvm.org/D72873
