	* exp_ch4.adb (Expand_N_Type_Conversion): Handle entities that are
	visible through limited-with context clauses. In addition, avoid an
	extra tag check that is not required when the class-wide
	designated types of the operand and target types are
	the same entity.
	(Tagged_Membership): Handle entities from the limited view.

	* gnatcmd.adb, make.adb, mlib-prj.adb, prj.ads, clean.adb,
	prj-nmsc.adb, prj-env.adb (File_Name_Data): removed
	(Spec_Or_Body): now a subtype of Source_Kind, to avoid using two
	different vocabularies for similar concepts (Impl/Body_Part and
	Spec/Specification).
	(Unit_Data): now points directly to a Source_Id, rather than duplicating
	some of the information in File_Name_Data. This also saves a bit of
	memory. However, since we are now using a pointer we need to test
	for null explicitly in several places of the code
