debug.adb: Document that -gnatdA automatically sets -gnatR3m

Browse Source 
* debug.adb: Document that -gnatdA automatically sets -gnatR3m

	* gnat1drv.adb (Gnat1drv): If debug flag A set, then automatically
	set -gnatR3m mode.

	* repinfo.adb (List_Rep_Info): Remove special handling of -gnatdA
	flag. No longer needed now that we handle this in gnat1drv.adb.

	* repinfo.ads: Minor reformatting
