The VSX testing variant in test/CodeGen/PowerPC/fma.ll had to be disabled because of unexpected behavior on many of the builders. I tracked this down to a situation that occurs when the VSX attribute is enabled for a target that disables the MI early scheduling pass. This patch adds -mcpu=pwr7 to make this predictable. The other issue will be addressed separately. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220171 91177308-0d34-0410-b5e6-96231b3b80d8
