	* ecore.cs (ImplicitReferenceConversion,
	ImplicitReferenceConversionExists): enum_type has to be handled
	like an object reference (implicit conversions exists from this to
	object), but the regular IsClass and IsValueType tests will never
	return true for this one.

	Also we use TypeManager.IsValueType instead of type.IsValueType,
	just for consistency with the rest of the code (this is only
	needed if we ever use the construct exposed by test-180.cs inside
	corlib, which we dont today).
