2012-03-20	LSR: fix IVUsers isSimplifiedLoopNest to perform a full domtree walk	Andrew Trick
	instead of skipping the current loop. My prior fix was incomplete because of an overzealous compile-time optimization: Better fix for: <rdar://problem/11049788> Segmentation fault: 11 in LoopStrengthReduce git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153131 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-16	LSR fix: Add isSimplifiedLoopNest to IVUsers analysis.	Andrew Trick
	Only record IVUsers that are dominated by simplified loop headers. Otherwise SCEVExpander will crash while looking for a preheader. I previously tried to work around this in LSR itself, but that was insufficient. This way, LSR can continue to run if some uses are not in simple loops, as long as we don't attempt to analyze those users.
