	* exp_ch9.adb: minor style fixes in comments.
	* sem_ch9.adb (Analyze_Delay_Relative): in GNATprove mode a delay
	relative statement introduces an implicit dependency on
	Ada.Real_Time.Clock_Time.
	* sem_util.adb: Minor reformatting.

	* sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
	must be treated as delayed aspect even if the expression is
	a literal, because the aspect affects the freezing and the
	elaboration of the object to which it applies.

	* exp_attr.adb (Constrained): Apply an access check (check that
	the prefix is not null) when the prefix denotes an object of an
	access type; that is, when there is an implicit dereference.
