The old PM already required this to work, and after a discussion with Hal this seems to really be the only sensible answer. The cache gracefully degrades as the IR is mutated, and most things which do this should already be incrementally updating the cache. This gets rid of a bunch of logic preserving and testing the invalidation of this analysis. llvm-svn: 292039

	invalid. This fixes use-after-free bugs that will arise with any interesting use of SCEV. I've added a dedicated test that works diligently to trigger these kinds of bugs in the new pass manager and also checks for them explicitly as well as triggering ASan failures when things go squirly. llvm-svn: 291426
