Speculatively revert commit 144124 (djg) in the hope that the 32 bit
dragonegg self-host buildbot will recover (it is complaining about object files differing between different build stages). Original commit message: Add a hack to the scheduler to disable pseudo-two-address dependencies in basic blocks containing calls. This works around a problem in which these artificial dependencies can get tied up in calling seqeunce scheduling in a way that makes the graph unschedulable with the current approach of using artificial physical register dependencies for calling sequences. This fixes PR11314. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144188 91177308-0d34-0410-b5e6-96231b3b80d8
