unitests: add some ARM TargetParser tests 

The ARM TargetParser would construct invalid StringRefs.  This would cause
asserts to trigger.  Add some tests in LLVM to ensure that we dont regress on
this in the future.  Although there is a test for this in clang, this ensures
that the changes would get caught in the same repository.
