Adding -verify-machineinstrs option to PowerPC tests Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624

Don't reserve R2 on Darwin/PPC 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. llvm-svn: 176868
