* use is_proc_far(procdefinition) instead of the current memory model to

determine whether to issue a near or a far call in ti8086callnode.do_call_ref.
This will allow adding support for near and far procvars in any memory model.

models, because in these models, interrupt procedures are treated as far and
an appropriate far call (or push cs+near call if in the same segment) is made
anyway

* a_call_ref functionality cannot be implemented efficiently at code generator level, because references need specific preparations at earlier points. Moved this support to tcgcallnode and its x86 descendants, and got rid of all ifdef's around.
...
+ x86 targets now directly call procedure variables located in references.
- a_call_ref method removed from tcg and thlcgobj.
