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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277624 91177308-0d34-0410-b5e6-96231b3b80d8
