	determined in the front-end, do not emit error message when
	by-reference actual is potentially unaligned.
	* gcc-interface/decl.c (gnat_to_gnu_field): Better error message for
	illegal representation clause on tagged or aliased component, or on
	by-reference type with forced alignment.

	* sem_ch12.adb (Analyze_Package_Instantiation): For an
	instantiation in an RCI library unit, omit the instance body
	if the RCI library unit is the instance itself (E.2.3(18)),
	but include the body if the instantiation is within the RCI
	declaration (12.3(12)).
