> Log message:
> make procedure find a little more conservative
> with regard to the 64bit longint changes
> in particular, don't change the 'set' variable,
> instead:
> 
> - in[i] := inreg(t, opA[i].mvar, set);
> - IF size > 1 THEN
> - set := set - RegSet{in[i]};
> + IF i = 0 THEN
> + in[i] := inreg(t, opA[i].mvar, set);
> + ELSE
> + in[i] := inreg(t, opA[i].mvar, set - RegSet{in[0]});
> END;
> 
> (though I was hoping to remove the assumption that size <= 2, I have increased)
> 
> put procedure pushnew1 and procedure pushnew back together as
> one procedure, with loops inside it
> it kind of looks like otherwise might have e.g. saved stuff to two temporary variables
> instead of one
> 
> rename procedure maybe_expand_stack to expand_stack
> it still only expands the stack sometimes, but I think the name is adequate
> 
> eliminate unnecessary variable 'size' in procedure discard
> 
> some whitespace/commenting changes
