Fix memory barrier position in g_atomic_int_get and g_atomic_pointer_get.

	* glib/gatomic.c: Fix memory barrier position in g_atomic_int_get
	and g_atomic_pointer_get. Add g_atomic_int_set and
	g_atomic_pointer_set implementations for the !DEFINE_WITH_MUTEXES &&
	G_ATOMIC_OP_MEMORY_BARRIER_NEEDED case, as well as defining them
	as functions (additionally to the macros in the header) for the
	!G_ATOMIC_OP_MEMORY_BARRIER_NEEDED case.
