	* sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
	sem_prag.adb to make it available for GNATprove; for concurrent
	types replace custom scope climbing with Scope_Same_Or_Within; for
	single concurrent objects add scope climbing (with Scope_Within),
	which was not there (that's the primary semantic change of this
	commit); also, when comparing a single concurrent object with
	its corresponding concurrent type rely on equality of types,
	not of objects (because that's simpler to code).
	* sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
	(Analyze_Global_Item): adjust special-casing of references to the
	current instance of a concurrent unit in the Global contracts
	of task types and single tasks objects; similar for references
	in the protected operations and entries of protected types and
	single protected objects (in all these cases the current instance
	behaves as an implicit parameter and must not be mentioned in
	the Global contract).

	* exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
	function calls returning a record within a subprogram call,
	for C generation.

	* sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
	name that designates the current instance of a child unit in its
	own body and appears as the prefix of a reference to an entity
	local to the child unit.
	* exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
	Minor reformatting.

	* sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
	may be intentional.

2017-09-08  Tristan Gingold  <gingold@adacore.com>

	* sem_warn.adb (Check_Unused_Withs): Remove test that disabled
	warnings on internal units in configurable run time mode.
