* No longer need to run die after instcombine
* Run new correlated expressions pass * Simplify the CFG (removing dead blocks, merging blocks, eliminating branches on constant booleans, etc) after correlated exprs pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3598 91177308-0d34-0410-b5e6-96231b3b80d8
