tree.h (TYPE_HASH): Use TYPE_UID. 

* tree.h (TYPE_HASH): Use TYPE_UID.
        (TREE_HASH): New macro with old definition of TYPE_HASH.
        * tree.c (build_type_attribute_variant): Use iterative_hash_object.
        (build_array_type, build_function_type): Likewise.
        (build_method_type_directly): Likewise.
        (build_offset_type, build_complex_type): Likewise.
        (type_hash_list, attribute_hash_list): Likewise. Now static.
        * except.c: s/TYPE_HASH/TREE_HASH/.
        * cp/tree.c (list_hash_pieces): s/TYPE_HASH/TREE_HASH/.
