Nick Lewycky dd643f26c4 Add a utility function that detects whether a loop is guaranteed to be finite. 
Use it to safely handle less-than-or-equals-to exit conditions in loops. These
also occur when the loop exit branch is exit on true because SCEV inverses the
icmp predicate.

Use it again to handle non-zero strides, but only with an unsigned comparison
in the exit condition.
