sem_util.adb (Wrong_Type): In any instance...

	* sem_util.adb (Wrong_Type): In any instance, do not emit error
	if type of expression is the partial view of the expected type.

2015-05-28  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Resolve_Actuals): a)  The replacement of formal
	names in named associations only needs to be done within an
	instance, on a call to a primitive of a formal derived type,
	where the actual subprogram may have different formal names than
	those of the primitive operation of the formal type.
	b) Defaulted parameters must be taken into account when obtaining
	the names of the formals of the actual subprogram being called.
