        PR fortran/28974
        * gfortran.h (gfc_expr): Add element which holds a splay-tree
        for the exclusive purpose of quick access to a constructor by
        offset.
        * data.c (find_con_by_offset): Use the splay tree for the search.
        (gfc_assign_data_value): Use the splay tree.
        (gfc_assign_data_value_range): ditto.
        * expr.c (gfc_get_expr): Initialize new element to null.
        (gfc_free_expr): Delete splay tree when deleting gfc_expr.
