Small optimization for the search of operator overloads. Add a flag "sto_has_generic" to all symtables that contain an operator overload (the flag propagates up the owning symtables) and check this flag when searching for units with operators.

Browse Source 
symconst.pas:
  + add "sto_has_operator" to "tsymtableoption"
pdecsub.pas:
  + include the flag "sto_has_operator" for all operator declarations and their owning symtables
htypechk.pas, tcallcandidates:
  * create_candidate_list: only check for operator overloads if the record does indeed declare some
  * collect_overloads_in_units: only check for operator overloads if the unit does indeed declare some
utils/ppudump.pp:
  + respect the new "sto_has_operator" flag
