allows ppcf128->int conversion to work with DeadInstructionElimination. This is now turned off but RM is harmless. It does not do a complete job of modeling the rounding mode. Revert marking MFCR as using all 7 CR subregisters; while correct, this caused the problem in PR 2964, plus the local RA crash noted in the comments. This was needed to make DeadInstructionElimination, but as we are not running that, it is backed out for now. Eventually it should go back in and the other problems fixed where they're broken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58391 91177308-0d34-0410-b5e6-96231b3b80d8
