* exp_util.adb (Get_Current_Value_Condition,
Set_Current_Value_Condition): Handle the case of expressions
with actions * exp_util.adb (Insert_Actions): Handle the case
of an expression with actions whose Actions list is empty.
* exp_util.adb (Remove_Side_Effects.Side_Effect_Free): An
expression with actions that has no Actions and whose Expression
is side effect free is itself side effect free.
* exp_util.adb (Remove_Side_Effects): Do not set an incorrect etype on
temporary 'R' (Def_Id), which is in general an access to Exp_Type, not
an Exp_Type.
* sem_res.adb (Resolve): For an expression with
actions, resolve the expression early. * sem_res.adb
(Resolve_Expression_With_Actions): Rewrite an expression with
actions whose value is compile time known and which has no
actions into just its expression, so that its constant value is
available downstream.
* sem_res.adb (Resolve_Short_Circuit):
Wrap the left operand in an expression with actions to contain
any required finalization actions.
* exp_ch4.adb (Expand_Expression_With_Actions): For an
expression with actions returning a Boolean expression, ensure
any finalization action is kept within the Actions list.
* sem_warn.adb (Check_References, Check_Unset_Reference): add
missing circuitry to handle expressions with actions.
* checks.adb (Ensure_Valid): For an expression with actions,
insert the validity check on the Expression.
* sem_ch13.adb (Build_Static_Predicate.Get_RList): An expression
with actions that has a non-empty Actions list is not static. An
expression with actions that has an empty Actions list has the
static ranges of its Expression.
* sem_util.adb (Has_No_Obvious_Side_Effects): An expression with
actions with an empty Actions list has no obvious side effects
if its Expression itsekf has no obvious side effects.
