   Description:
      Verifies the proper semantics for statements, checking expressions already
      semantically analyzed individually, collectively, checking label defs and
      refs, and so on.	Uses ffebad to indicate errors in semantics.

      In many cases, both a token and a keyword (ffestrFirst, ffestrSecond,
      or ffestrOther) is provided.  ONLY USE THE TOKEN as a pointer to the
      source-code location for an error message or similar; use the keyword
      as the semantic matching for the token, since the token's text might
      not match the keyword's code.  For example, INTENT(IN OUT) A in free
      source form passes to ffestc_R519_start the token "IN" but the keyword
      FFESTR_otherINOUT, and the latter is correct.

      Generally, either a single ffestc function handles an entire statement,
      in which case its name is ffestc_xyz_, or more than one function is
      needed, in which case its names are ffestc_xyz_start_,
      ffestc_xyz_item_ or ffestc_xyz_item_abc_, and ffestc_xyz_finish_.
      The caller must call _start_ before calling any _item_ functions, and
      must call _finish_ afterwards.  If it is clearly a syntactic matter as
      to restrictions on the number and variety of _item_ calls, then the caller
      should report any errors and ffestc_ should presume it has been taken
      care of and handle any semantic problems with grace and no error messages.
      If the permitted number and variety of _item_ calls has some basis in
      semantics, then the caller should not generate any messages and ffestc
      should do all the checking.

      A few ffestc functions have names rather than grammar numbers, like
      ffestc_elsewhere and ffestc_end.	These are cases where the actual
      statement depends on its context rather than just its form; ELSE WHERE
      may be the obvious (WHERE...ELSE WHERE...END WHERE) or something a little
      more subtle (WHERE: IF THEN...ELSE WHERE...END IF WHERE).	 The actual
      ffestc functions do exist and do work, but may or may not be invoked
      by ffestb depending on whether some form of resolution is possible.
      For example, ffestc_R1103 end-program-stmt is reachable directly when
      END PROGRAM [name] is specified, or via ffestc_end when END is specified
      and the context is a main program.  So ffestc_xyz_ should make a quick
      determination of the context and pick the appropriate ffestc_Nxyz_
      function to invoke, without a lot of ceremony.
