gcc/
	* machmode.h (mode_size): Change from unsigned short to
	poly_uint16_pod.
	(mode_to_bytes): Return a poly_uint16 rather than an unsigned short.
	(GET_MODE_SIZE): Return a constant if ONLY_FIXED_SIZE_MODES,
	or if measurement_type is not polynomial.
	(fixed_size_mode::includes_p): Check for constant-sized modes.
	* genmodes.c (emit_mode_size_inline): Make mode_size_inline
	return a poly_uint16 rather than an unsigned short.
	(emit_mode_size): Change the type of mode_size from unsigned short
	to poly_uint16_pod.  Use ZERO_COEFFS for the initializer.
	(emit_mode_adjustments): Cope with polynomial vector sizes.
	* lto-streamer-in.c (lto_input_mode_table): Use bp_unpack_poly_value
	for GET_MODE_SIZE.
