patch restricting the X % -Y -> X % Y transformation to when it's safe
This proposed patch restricts the X % -Y -> X % Y transformation to cases when
we can be certain that it doesn't result in undefined behaviour, i.e. when Y !=
1 or X != INT_MIN. Passes bootstrap and testsuite on x86_64-linux so far.
