*	[LV] Run loop-simplify and LCSSA explicitly instead of "requiring" them	Michael Kuperstein	2017-01-19	1	-8/+4
\| \| \| \| \| \| \| \| \| \| \| \|	This changes the vectorizer to explicitly use the loopsimplify and lcssa utils, instead of "requiring" the transformations as if they were analyses. This is not NFC, since it changes the LCSSA behavior - we no longer run LCSSA for all loops, but rather only for the loops we expect to modify.

*	[LV] Don't panic when encountering the IV of an outer loop.	Michael Kuperstein	2017-01-10	1	-0/+64
	Bail out instead of asserting when we encounter this situation, which can actually happen. The reason the test uses the new PM is that the "bad" phi, incidentally, gets cleaned up by LoopSimplify. But LICM can create this kind of phi and preserve loop simplify form, so the cleanup has no chance to run. This fixes PR31190. We may want to solve this in a less conservative manner, since this phi is actually uniform within the inner loop (or we may want LICM to output a cleaner promotion to begin with).
