These new calls should not prevent NOSPLIT promotion, like the old ones. These new calls should not prevent racefuncenter/exit removal. (The latter was already true, as the new calls are not yet lowered to StaticCalls at the point where racefuncenter/exit removal is done.) Add tests to make sure we don't regress (again).
