New Revision: 169604

URL: http://llvm.org/viewvc/llvm-project?rev=169604&view=rev
Log:
The test unconditionally assumes a particular cpu has a backend build in the target.
Buildbots for some hosts may choose to build only their own backend in order to
maximise testing-turnaround time. Move the test into a prefixed directory so
lit's standard "backend specific" suppression can be done.
