This commit introduces two fake instructions MORESTACK_RET and
MORESTACK_RET_RESTORE_R10; which are lowered to a RET and a RET followed by a MOV respectively. Having a fake instruction prevents the verifier from seeing a MachineBasicBlock end with a non-terminator (MOV). It also prevents the rather eccentric case of a MachineBasicBlock ending with RET but having successors nevertheless. Patch by Sanjoy Das. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143062 91177308-0d34-0410-b5e6-96231b3b80d8
