	* sem_util.adb (Copy_Node_With_Replacement):
	Update the Renamed_Object field of a replicated object renaming
	declaration.

2017-09-08  Patrick Bernardi  <bernardi@adacore.com>

	* exp_ch9.adb (Is_Pure_Barrier): Allow type
	conversions and components of objects. Simplified the detection
	of the Count attribute by identifying the corresponding run-time
	calls.

	* exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
	sem_type.adb, sinfo.ads: Minor reformatting.

	* freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
	of Freeze_Profile, used to inhibit the freezing of the profile
	of an expression function declared within a nested package, when
	some type in the profile depends on a private type declared in
	an enclosing package.

	* gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
	the subunit case. It's still OK to set it in the "missing subunits"
	case, because that won't cause the obsolete .ali files that cause
	confusion.

	* sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
	unclear why this didn't cause a warning.
	* a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
	pragmas. It's unclear why this didn't cause an error.
