* sem_ch12.adb:

	(Analyze_generic_subprogram_Declaration): Set outer_generic_scope,
	to prevent freezing within formal packages.
	(Freeze_Subprogram_Body): If body comes from another instance that
	appeared before its own body, place freeze node at end of current
	declarative part, to prevent a back-end crash.
	(Inline_Instance_Body): Handle properly a package instance within
	a subprogram instance that is a child unit.
