[PATCH] Fix PR55555

The following patch fixes a miscompilation due to bogus loop iteration bound derived from array accesses in an inner loop. idx_infer_loop_bounds analyzes the evoultion of an SSA name with respect to a loop it is not defined in - which seems to lead to random weird behavior. The correct thing to
