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).

Write out the far data space as well as the near.
...
This causes the Objective-QC structs to be emitted now that they havve been
moved to the far data space. Relocs are broken, though.

Protect the name passed into emit_struct().
...
The name passed into emit_struct is sometimes created via va(), but the
struct creation code also uses va. This makes a mess of names.

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.
