    * tree.h (VECTOR_CST_NELTS): Use part number of types again.
    (struct tree_vector): Adjust GTY length.
    * tree.c (make_vector_stat): Don't set VECTOR_CST_NELTS.

    * gengtype.c (struct walk_type_data): Add in_record_p and loopcounter
    members.
    (walk_type, <TYPE_POINTER, TYPE_ARRAY>): Handle case where our
    caller emitted the length calulation already.
    (walk_type, <TYPE_UNION, TYPE_STRUCT>): Emit length calculations
