    OpenMP: Duplicate checking for map clauses in Fortran (PR107214)

    This patch adds duplicate checking for OpenMP "map" clauses, taking some
    cues from the implementation for C in c-typeck.cc:c_finish_omp_clauses
    (and similar for C++).

    In addition to the existing use of the "mark" and "comp_mark" bitfields
    in the gfc_symbol structure, the patch adds several new bits handling
    duplicate checking within various categories of clause types.  If "mark"
    is being used for map clauses, we need to use different bits for other
    clauses for cases where "map" and some other clause can refer to the
    same symbol (e.g. "map(n) shared(n)").
