Now that only the register-scavenger version of the CR spilling code remains, we no longer need the Darwin R2 hack. Darwin can use R0 as a spare register in any case where the System V ABI uses it (R0 is special architecturally, and so is reserved under all common ABIs). A few test cases needed to be updated to reflect the register-allocation changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176868 91177308-0d34-0410-b5e6-96231b3b80d8
