Try to avoid mutually exclusive features. Don't use a real default GPU, and use a fake "generic". The goal is to make it easier to see which set of features are incompatible between feature strings. Most of the test changes are due to random scheduling changes from not having a default fullspeed model. llvm-svn: 310258
