* reworked handling of defined/declared symbols in llvm: we now automatically

    generate declarations when external symbols are referred in a taillvm
    instruction
  * added "declared" field to tasmsymbol for llvm to make avoid declaring a
    symbol multiple times (harmless, but unnecessary)
  * all kinds of declarations/definitions are now handled using the new
    taillvmdecl, the old separate types have been removed
