Justin Lebar 97cc80a0e8 [NVPTX] Test that MachineSink won't sink across llvm.cuda.syncthreads.
Summary:
The syncthreads MI is modeled as mayread/maywrite -- convergence doesn't
even come into play here.  Nonetheless this property is highly implicit
in the tablegen files, so a test seems appropriate.
