	* types.ads: Clean up obsolete comments
	* tbuild.adb: Minor reformatting.
	* exp_ch5.adb, sem_intr.adb, sem_ch10.adb, rtsfind.adb, s-shasto.adb,
	exp_strm.adb, aa_drive.adb: Minor reformatting.
	* sem_res.adb (Is_Predefined_Operator): An operator that is an imported
	intrinsic with an Interface_Name denotes an imported back-end builtin,
	and must be rewritten into a call, not left in the tree as an operator,
	so return False in that case.
