 	index type instead of base type for the bounds. Set TYPE_ARRAY_MAX_SIZE
	of the array to the maximum size.
	<E_Array_Subtype>: Create an extra subtype using the index type of the
	base array type for self-referential bounds.  Use update_n_elem to

 	subtypes on the self-referential bounds.
	<tcc_binary>: Rewrite.  Deal with "negative value" in unsigned types.
	<tcc_expression>: Likewise.
	* gcc-interface/utils2.c (compare_arrays): Retrieve the original bounds
