Stop trying to have instcombine preserve LCSSA form: this was not effective in avoiding recomputation of LCSSA form; the widespread use of instsimplify (which looks through phi nodes) means it was not preserving LCSSA form anyway; and instcombine is no longer scheduled in the middle of the loop passes so this doesn't matter anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130301 91177308-0d34-0410-b5e6-96231b3b80d8
