The current value propagation applies only to assignable objects and
doesn't make sense for subprogram entities. This was a mistake
introduced when extending the current value propagation years ago.
Cleanup related to fixing interference between expansion of attribute
Loop_Entry and current value propagation.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* sem_attr.adb (Address_Checks): Remove call to
Kill_Current_Values for subprogram entities, because this
routine only does something for object entities.
