Corresponding_Spec on the body created for a null procedure. Add ???
comment. Remove New_Copy_Tree call on body argument to
Set_Body_To_Inline.
* exp_ch6.adb (Add_Simple_Call_By_Copy_Code): For an out parameter with
discriminants, use the type of the actual as well, because the
discriminants may be read by the called subprogram.
* sem_ch3.adb (Access_Type_Declaration): If the designated type is an
access type we do not need to handle non-limited views.
