The primitive can send #initialize just like perform: does.  It does not
even need to check if it is empty, _gst_send_message_internal will do
that.  You save the creation of the MethodContext; the disadvantage is
that #new will not appear in the backtrace, and that the JIT will not be
able to use an inline cache.
