Avoid freeing an operand twice.

Write the linker output to progs.dat.
...
There is much breakage, but qfcc now produces a progs.dat from either
progs.src or object files. Better yet, the progs.src result is passed
through the linker, removing much duplicate code.

Handle relocs.
...
With this, the building of the work qfo seems to be almost finished, just
the special defs to go. Next step will be to stitch all the parts of the
work qfo into a real qfo.
However, still have to fix the relocs for the type descriptors, but they
are not critical to the linker's functioning.

Split the type processing into two passes.

This allows all duplicate types to be "merged" before adding any new
