George Burgess IV 591266dd81 [MSSA] Fix a caching bug. ... This fixes a bug where we'd sometimes cache overly-conservative results with our walker. This bug was made more obvious by r277480, which makes our cache far more spotty than it was. Test case is llvm-unit, because we're likely going to use CachingWalker only for def optimization in the future. The bug stems from that there was a place where the walker assumed that `DefNode.Last` was a valid target to cache to when failing to optimize phis. This is sometimes incorrect if we have a cache hit. The fix is to use the thing we *can* assume is a valid target to cache to. :) llvm-svn: 277559		2016-08-03 01:22:19 +00:00
