Fix PHIElimination optimization that uses MBB->getBasicBlock. The BasicBlock associated with a MachineBasicBlock does not necessarily correspond to the code in the MBB. Don't insert a new IR BasicBlock when splitting critical edges. We are not supposed to modify the IR during codegen, and we should be able to do just fine with a NULL BB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88707 91177308-0d34-0410-b5e6-96231b3b80d8
