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).

Fix sign extend to long. When coming from sbyte, we used to generate:

movsbl 4(%esp), %eax
movl %eax, %edx

Now we generate:
movsbl 4(%esp), %eax
movl %eax, %edx
sarl $31, %edx
Which is right.
