[dev.typeparams] runtime: use func() for deferred functions
Prior to regabi, a deferred function could have any signature, so the
runtime always manipulated them as funcvals. Now, a deferred function
is always func(). Hence, this CL makes the runtime's manipulation of
deferred functions more type-safe by using func() directly instead of
*funcval.
