x86: Use HOST_WIDE_INT_(0|M1)U to initialize unsigned HOST_WIDE_INT

Use HOST_WIDE_INT_0U, instead of 0, HOST_WIDE_INT_M1U, instead of -1, to
initialize unsigned HOST_WIDE_INT.

	* config/i386/i386-expand.cc (ix86_expand_set_or_cpymem): Use
	HOST_WIDE_INT_0U and HOST_WIDE_INT_M1U to initialize unsigned
	HOST_WIDE_INT.
