— Rework forwarding API and ABI.
It matches the Apple API and ABI now and the forwarding handler itself
determines whether it should forward or not.This moves handling of +[resolve{Class,Instance}Method:] to the runtime
and allows adding new kinds of forwarding without changing the runtime.Also fixes a potential stack problem in the forwarding for MIPS. (user: js, size: 1724) [annotate] [blame] [check-ins using]
