Add a test case for PR8385.

"struct{template struct{" would fail an assertion.

This assertion failure seems to have gone away somewhere along the line so
here's a test to make sure we don't regress. We still accept some very weird
explicit template 'instantiations' ("template int;", anyone) but at least we're
not asserting/crashing here.
