Fix fall outs from my recent change on how carry bit is modeled during isel.
Now the 'S' instructions, e.g. ADDS, treat S bit as optional operand as well. Also fix isel hook to correctly set the optional operand. rdar://10073745 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139157 91177308-0d34-0410-b5e6-96231b3b80d8
