move resolve_method code from word to mom

rather make resolve an instruction.
Since it was coded in risc anyway, we not only save the setup and call
But also makes the mom instruction flow clearer
The method really came from not wanting to code it in risc, but with
the Builder, that is now surprisingly painless
