fold-const.c (int_binop_types_match_p): New function.

	* fold-const.c (int_binop_types_match_p): New function.
	(size_binop): Relax constraint that both arguments must both have
	exactly the same sizetype type.  Instead use int_binop_types_match_p.
	(size_diffop): Likewise.

	(make_range): Use build_int_cst instead of fold_convert.
	(fold_cond_expr_with_comparison): Use build_int_cst to construct
	integer constants of the correct type.
	(fold_div_compare): Likewise.
	(fold_single_bit_test): Likewise.
	(fold_binary): Likewise.
	* stor-layout.c (layout_type) <VECTOR_TYPE>: Ensure that TYPE_SIZE
	has type bitsizetype and TYPE_SIZE_UNIT has type sizetype.
