	* sem_res.adb (Resolve_Call): If the call is rewritten as an indexed of
	a parameterless function call, preserve parentheses of original
	expression, for proper handling by pretty printer.
	* sem_attr.adb (Analyze_Attribute, case 'Old): Add guard to Process
	procedure, to handle quietly identifiers that have no entity names.
	* exp_util.adb (Get_Current_Value_Condition): If the parent of an
	elsif_part is missing, it has been rewritten as a nested if, and there
	is no useful information on the current value of the variable.
