* sem_attr.adb (Analyze_Attribute_Old_Result): The attributes can
appear in the postcondition of a subprogram renaming declaration,
when the renamed entity is an attribute reference that is a
function (such as 'Value).
* sem_attr.adb (Eval_Attribute): It doesn't
need to be static, just known at compile time, so use
Compile_Time_Known_Value instead of Is_Static_Expression.
This is an efficiency improvement over the previous bug fix.
* sem_ch13.adb (Analyze_One_Aspect): Use Original_Node to detect
illegal aspects on subprogram renaming declarations that may
have been rewritten as bodies.

folded. Fix it so it makes that assumption only when X denotes
a STATIC constant.

it's covered by the 'while' condition.
* checks.adb (Apply_Selected_Range_Checks): Remove useless
condition "or else not Checks_On".
(Selected_Range_Checks):
Initialize Known_LB and Known_HB to False, because they are

condition "not R_Type_Is_Anon_Access" to an Assert.
* sem_elim.adb (Line_Num_Match): Moved redundant condition
"Sloc_Trace (Idx) = '['" to an Assert.
* sem_util.adb (Compile_Time_Constraint_Error): Change "J" to
"J - 1". This code is trying to replace "?" with "<", but not if
the "?" is quoted, as in "'?", so we want to check the PREVIOUS
character for '''.
* snames.adb-tmpl (Is_Pragma_Name): Remove useless condition
"or else N = Name_Relative_Deadline". It's useless because
Name_Relative_Deadline is in the range First_Pragma_Name
