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

; Test several VSX FMA mutation opportunities. The first one isn't a

; reasonable transformation because the killed product register is the
|

; same as the FMA target register. The second one is legal. The third

; one doesn't fit the feeding-copy pattern.
