Bill Currie 208cba85eb [gamecode] Move return buffer to end of progs memory map 
With the return buffer in progs_t, it could not be addressed by the
progs on 64-bit machines (this was intentional, actually), but in order
to get obj_msg_sendv working properly, I needed a way to "bounce" the
return address of a calling function to the called function. The
cleanest solution I could think of was to add a mode to the with
instruction allowing the return pointer to be loaded into a register and
then calling the function with a 0 offset for the return value but using
the relevant register (next few commits). Testing promptly segfaulted
due to the 64-bit offset not fitting into a 32-bit value.
