	* sem_ch3.adb, sem_ch5.adb, sem_ch9.adb, sem_prag.adb, sem.ads,
	sem_util.adb, sem_util.ads, sem_res.adb, sem_ch2.adb, sem_ch4.adb,
	sem_ch6.adb, sem_ch11.adb: Add semantic flag In_Pre_Post_Expression to
	indicate that we are in a precondition or postcondition. This is used in
	Mark_Non_ALFA_Subprogram (renaming of Mark_Non_ALFA_Subprogram_Body) to
	decide whether to flag the spec or body of the current subprogram as
	not in ALFA.

	* impunit.adb: Add Ada.Execution_Time.Interrupts in the Ada2012 package
	list.
	* a-extiin.ads: New file.

	* a-direct.adb (Rename): Implement AI05-0231-1. In particular, Rename
	now raises Name_Error instead of Use_Error in certain cases. The other
	parts of this AI were already implemented properly.
