Generate only one daglabel for value operands.
...
As each value is now unique, their labels can also be unique, which will
improve CSE.

Make values independent objects.

values are now uniquely allocated (for the current object file). With
this, constants in dags will work.

Rework build_switch to use initialize_def.

This required support for label reference expressions, whose purpose is to
represent the address of a label.

Bring back the unsigned type (PROGS version bump)
...
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

It is now mainly for converting __FILE__ etc, handling expression symbols,

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.

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.
