ada: Add 'artificial_p' parameter to build_unc_object_type

This adds an 'artificial_p' parameter to build_unc_object_type, so
that the artificiality of the type can be propagated to
create_type_decl.  This will affect the namelessness of the type in a
subsequent patch.

gcc/ada/ChangeLog:

	* gcc-interface/decl.cc (gnat_to_gnu_entity): Pass artificial_p to
	build_unc_object_type.
	* gcc-interface/gigi.h (build_unc_object_type): Update.
	* gcc-interface/utils.cc (build_unc_object_type) Add artificial_p
	parameter.
	(build_unc_object_type_from_ptr): Update.
