[CUDA] Rework tests now that we emit deferred diagnostics during sema. Test-only change.

Summary:
Previously we had to split out a lot of our tests into a test that
checked only immediate errors and a test that checked only deferred
errors.  This was because, if you emitted any immediate errors, we
wouldn't run codegen, where the deferred errors were emitted.

We've fixed this, and now emit deferred errors during sema.  This lets
us merge a bunch of tests, and lets us convert some other tests to
-fsyntax-only.
