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.
