- Replace CodeStubArguments::GetLength() with GetLengthWithReceiver()
and GetLengthWithoutReceiver()
- Introduce and use Torque macros to load the formal parameter count
(with and without receiver).
- Add actual_count to Torque arguments structure for cases where the
argument count is not used, but just forwarded to other builtins.
