This provides the first pass of assembler internals for a new, richer,
backend interface. It also reduces the amount of data carried in
function parameters inside the assembler.
The new interface is in the form of a structure, which will contain
substantially more information that the previous interface. This will
allow things like ELF GOT32X and Mach-O X86_64_RELOC_BRANCH
relocations to be reliably emitted.
This provides the initial set of structures. Future additions should
include:
1. Pass down the base symbol, if any.
2. Segments should be a structure rather than a number, and the
horrible hack of adding one for a segment reference should be
removed (OUT_SEGMENT replaces it.)
