CHANGES:
File: lib/Transforms/Scalar/CorrelatedValuePropagation.cpp
At: Fri 29 Oct 2010 14:07:37
Changed By: resistor
Comments: Give up on doing in-line instruction simplification during correlated value propagation.  Instruction simplification
needs to be guaranteed never to be run on an unreachable block.  However, earlier block simplifications may have
changed the CFG to make block that were reachable when we began our iteration unreachable by the time we try to
simplify them. (Note that this also means that our depth-first iterators were potentially being invalidated).

This should not have a large impact on code quality, since later runs of instcombine should pick up these simplifications.
Fixes PR8506.
