Give functions their own defspace.

Give defspaces some backing memory.
...
I'm not sure I want all defspaces to have backing memory, but this will do
for now.

Simplify def handling, use far data.
...
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

Get qfcc running again.

It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)

This seems to be better for complicated code. switch seems to be better
suited for relatively simple code.

Nuke bind expressions.

Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).
