*	LoopUnroll: Create sub-loops in LoopInfo	Duncan P. N. Exon Smith	2014-10-07	1	-0/+35
	`LoopUnrollPass` says that it preserves `LoopInfo` -- make it so. In particular, tell `LoopInfo` about copies of inner loops when unrolling the outer loop. Conservatively, also tell `ScalarEvolution` to forget about the original versions of these loops, since their inputs may have changed. Fixes PR20987. llvm-svn: 219241
