Don't apply on PPC64 the 32bit ADDIC optimizations as there's no overflow with 32bit values. llvm-svn: 133439

; Check that the ADDIC optimizations are not applied on PPC64
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
