Fix a bug in the dead stores checker reported in the following email: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-July/002157.html Essentially the observer mechanism in LiveVariables was observing block-level expressions multiple times, leading to a case where the dead store checker could see a value as dead when it was really live. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53115 91177308-0d34-0410-b5e6-96231b3b80d8
