* tcgcallnode.pass_generate_code: pass the correct vmt pointer type parameter to
  location_force_reg when generating code for a call to a virtual class method,
  called through a class reference var. This bug went unnoticed so far, because
  on all platforms, except i8086 medium and compact memory models, the size of
  a vmt pointer is the same as the size of a procvar. Even in the i8086 medium
  and compact memory models, the previous code would generate correct code,
  because thlcg2ll.a_load_loc_reg uses loc.size (which was correct) in the case
  when fromsize=tosize (both of which were wrong, but equal), due to the check
  in hlcg2ll.pas:555. Thanks to Jonas for finding this bug!
