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.

Point the near and far data spaced into the merged data space.

This lets the relocations work on the final data without having to adjust
their locations.

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.

the missing __obj_exec_class def in qwaq.

Remove the dirty hack used for accessing params and the return value.
...
Instead of using the equivalent of *(float*)&.return, now use the
equivalent of (float).return. No conversion is done in the "cast".
NOTE: this sort of cast should be separated from normal casts.

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.

Adjust the offsets of ivars in derived classes.

As ivar structs are not independent, their starting offset is not
necessarily zero (almost never will be for derived classes).

Initialize current_symtab in class_init() when necessary.
...
If an objective-qc symbol is the first token to be read, class_init() is
called before the parser gets a chance to perform the initialization
action. However, class_init() setting current_symtab if the first
objective-qc symbol is seen in a function body would be bad.
