	* exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
	uses of 'Image and related attributes as having side effects in
	order to avoid replicating such uses.
	* pprint.ads (Expression_Image) Add new generic formal flag
	Hide_Temp_Derefs.  The flag defaults to False; CodePeer will
	(eventually) override the default.
	* pprint.adb (Expression_Image) If the new flag is set, then
	suppress the ".all" suffix when displaying a dereference whose
	prefix is a use of a value-capturing compiler temp of the sort
	generated by Expr_Util.Remove_Side_Effects .
	* exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,
	sem_ch7.adb, sem_dim.adb, sem_util.adb, sem_util.ads, sem_warn.adb:
	Minor reformatting.
	* inline.adb: Minor wording change.
