	* exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
	attribute Mechanism_Code is applied to renamed subprogram, modify
	prefix to point to base subprogram.
	Max/Min attributes now violate Restriction No_Implicit_Conditionals

	* sinfo.ads: Document that Mechanism_Code cannot be applied to
	renamed subprograms so that the front-end must replace the prefix
	appropriately.
