go/types: guard against checking instantiation when generics is disabled When type checking t[_], where t is a type name, it was possible to leak an error message related to generics. Fix this by guarding on typeparams.Enabled. In order to test this fix, we need to be able to run the new go/types test only if type parameters are disabled. Introduce the .go1 test data suffix (similar to .go2) to control this behavior. Originally found via fuzzing, though the test case was manually simplified.
