Max Kazantsev ff635da3c0 [IRCE] Do not process empty safe ranges ... IRCE should not apply when the safe iteration range is proved to be empty. In this case we do unneeded job creating pre/post loops and then never go to the main loop. This patch makes IRCE not apply to empty safe ranges, adds test for this situation and also modifies one of existing tests where it used to happen slightly.
