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

DAGCombiner: Replace store of FP constant after attemping store merges If storing multiple FP constants, some subset of the stores would be replaced with integers due to visit order, so MergeConsecutiveStores would only partially merge these. llvm-svn: 248169
