of parent procedures which are implicitly accessed from within
    nested procedures for range checking purposes as non-regable in
    the resulttype pass of the nested procedure (as opposed to in its
    pass1/pass2, because by then the regvar assignment of the parent
    procedure is already finished) (mantis #8975)
  * related fix regarding checking whether the high parameter actually
    exists (must check calling convention of the procedure to which the
    high parameter belongs, which is not the same as checking that of
    the current procedure in case of nested procedures)
