Store the initializer expression in the def.

Initially, this will be used for collecting the targets of a jumpb
instruction.

Take care of relocs when defining external defs.
...
For most of the cases, some relocs may have been lost, but they were
certainly lost for type encodings. Now that all seems to be fixed.

Allow field aliasing.
...
Initializing a field variable to another field will set the new field to
point to the same location. No type checking is done.
eg:
.SEL thinkMethod = think;

Allocate space for temp defs using size rather than type.
...
Statement operands throw away the high level type information, so store
type size in the operand and use this size for allocating space for temps
rather than using the low-level type.

Preserve relocs across def churning.
...
Freeing then re-allocating a def to change its storage from external is
really not the right way to do it, but for now this fixes the loss of the
relocs. With this, the menus seem to work :)

field def tables in the linker.

Optionally create *_[xyz] symbols for accessing vector components.
...
"vector-components" in code options controls this feature. The default is
off for advanced code and on for traditional code. Disabling
vector-components prevents the comonent names polluting the namespace and
reduces the number of globals needed for vector fields if the components
of that field are never used.

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.

object files in the new scheme.

Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.

That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.
