tree.c (build_int_cst_wide): Add an assertion (gcc_unreachable) when attempting to build INTEGER_CSTs of...


	* tree.c (build_int_cst_wide): Add an assertion (gcc_unreachable)
	when attempting to build INTEGER_CSTs of non-integral types.
	* expmed.c (make_tree): Use the correct type, i.e. the inner
	type, when constructing the individual elements of a CONST_VECTOR.
