* sem_util.ads, sem_util.adb (Side_Effect_Free_Statements,
Side_Effect_Free_Loop): New functions.
(Has_Non_Null_Statements): Consider N_Call_Marker as a null
statement.
* sem_ch5.adb (Analyze_Loop_Parameter_Specification): Call
Set_Is_Null_Loop even inside a generic instantiation.
(Analyze_Loop_Statement): Mark for removal loops with no side
effects.
