[Ada] Bad warning: Size in Compile_Time_Error in nested instance
2019-12-16 Bob Duff <duff@adacore.com>
gcc/ada/
* sem_attr.adb (Analyze_Attribute): Use Known_RM_Size. But we
still need Size_Known_At_Compile_Time, because when the size
really is known, sometimes only one or the other of these is
True.
