now works in instructions which require a 2-bit or 3-bit INTcc code. Incidentally, that means that the representation of INTcc registers is now the same in both integer and FP instructions. Thus, code became much simpler and cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7185 91177308-0d34-0410-b5e6-96231b3b80d8
