Allow defs to specify use of offset relocations.
...
Access to struct fields in near data can be done using only one operand,
but offset relocs need to be used. However, as not all defs want offset
relocs, a flag has been added to the def struct.

Emit pointers properly.
...
Rename ReuseConstant to emit_value and use emit_value to emit any non-short
constant. This fixes the null pointer in the call to __obj_exec_class.

Make relocation records store the space of the relocation.
...
The space is meaningless for op_* relocations as they are always in the
code space, but def_* relocations need to know which space holds the
location to be adjusted.

Give short values special treatment.
...
As a short value fits directly into a statement, it needs a fake def that
holds its value in the def's offset in order for the value to be written to
the statement.

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.

Don't use the true void return in traditional mode.
Prefer the true void return over "done" at the end of functions.

no label at the end of the function.
