Remove unsafe is_record/test_arity optimizations
The type optimizations for is_record and test_arity checked whether the arity was equal to the size stored in the type information, which is incorrect since said size is the *minimum* size of the tuple (as determined by previous instructions) and not its exact size. A future patch to the 'master' branch will restore these optimizations in a safe manner.
