	* sem_ch4.adb (Remove_Abstract_Operations): Do not apply preference
	rule prematurely when operands are universal, remaining ambiguities
	will be removed during resolution.
	Code cleanup.

	* sem_type.adb (Disambiguate): In Ada95 mode, discard interpretations
	that are Ada 2005 functions.
	(Has_Abstract_Interpretation): Subsidiary to
	Remove_Conversions, to remove ambiguities caused by abstract operations
	on numeric types when operands are universal.
