	* ghost.adb (Mark_Ghost_Clause): New routine.
	(Prune_Node): Do not prune compilation unit nodes.
	(Remove_Ignored_Ghost_Code): Prune the compilation unit node directly.
	This does not touch the node itself, but does prune all its fields.
	* ghost.ads (Mark_Ghost_Clause): New routine.
	* sem_ch8.adb (Analyze_Use_Package): Emit an error when a use
	package clause mentions Ghost and non-Ghost packages. Mark a
	use package clause as Ghost when it mentions a Ghost package.
	(Analyze_Use_Type): Emit an error when a use type clause mentions
	Ghost and non-Ghost types. Mark a use type clause as Ghost when
	it mentions a Ghost type.
	* sem_ch10.adb (Analyze_With_Clause): Mark a with clause as
	Ghost when it withs a Ghost unit.

	* sem_res.adb (Resolve_Call): If a function call
	returns a limited view of a type and at the point of the call the
	function is not declared in the extended main unit then replace
	it with the non-limited view, which must be available. If the
	called function is in the extended main unit then no action is
	needed since the back-end handles this case.

	* sem_ch7.adb (Contains_Subp_Or_Const_Refs): Rename into...
	(Contains_Subprograms_Refs): ...this.  Adjust comment
	for constants.	(Is_Subp_Or_Const_Ref): Rename into...
	(Is_Subprogram_Ref): ...this.
	(Has_Referencer): Rename Has_Non_Subp_Const_Referencer variable into
	Has_Non_Subprograms_Referencer and adjust comment.  Remove
	incorrect shortcut for package declarations and bodies.

	* sem_ch3.adb (Complete_Private_Subtype): If the scope of the
	base type differs from that of the completion and the private
	subtype is an itype (created for a constraint on an access
	type e.g.), set Delayed_Freeze on both to prevent out-of-scope
	anomalies in gigi.

	* sem_ch6.adb (Analyze_Subprogram_Body_Helper):
	When inheriting the SPARK_Mode of a prior expression function,
	look at the properly resolved entity rather than the initial
	candidate which may denote a homonym.

	* sem_prag.adb (Rewrite_Assertion_Kind): If the name is
	Precondition or Postcondition, and the context is pragma
	Check_Policy, indicate that this Pre-Ada2012 usage is deprecated
	and suggest the standard names Assertion_Policy /Pre /Post
	instead.
