Revamp supported ops. Instead of just being supported or not, we now keep
...
track of how to deal with it, and provide the target with a hook that they
can use to legalize arbitrary operations in arbitrary ways.
Implement custom lowering for a couple of ops, implement promotion for select
operations (which x86 needs).
