Fix crash in bounds checking.
In r337830 I added SCEV checks to enable us to insert fewer bounds checks. Unfortunately, this sometimes crashes when multiple bounds checks are added due to SCEV caching issues. This patch splits the bounds checking pass into two phases, one that computes all the conditions (using SCEV checks) and the other that adds the new instructions.
