Reimplement selector expressions to work with far data.

They currently execute a lea instruction every method call, but the

Allow cast expressions to be lvalues.

These really need to be alias expressions rather than cast expressions
so the two can be separated as cast expressions should not be lvalues.

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.

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.
