    ada: Fix for quantified expressions in Exceptional_Cases
    
    When detecting illegal uses of formal parameters of the current
    subprogram in contract of its Exceptional_Cases, we relied on the
    Current_Scope. However, quantified expressions introduce an implicit
    scope, which we need to take into account.

            * sem_res.adb (Resolve_Entity_Name): Ignore implicit loop scopes
            introduced by quantified expressions.
