of bounds of slice for various kinds of discrete ranges.

Activation_Is_Complete reads it, and that can be called

* sem_res.adb (Set_Slice_Subtype): Handle properly a discrete
range given by a subtype indication, and force evaluation of
the bounds, as for a simple range.
* exp_util.adb (Evaluate_Slice_Bounds): Utility to force evaluation
of bounds of slice for various kinds of discrete ranges.
(Evaluate_Name, Evaluate_Subtype_From_Expr): use
Evaluate_Slice_Bounds.

* s-taskin.ads (Activator): Make this Atomic, because
Activation_Is_Complete reads it, and that can be called
from any task. Previously, this component was only
modified by the activator before activation, and by
Self after activation.

Activation_Is_Complete): Implement these missing functions.
