    ada: Emit SCOs for nested decisions in quantified expressions
    
    The tree traversal for decision SCO emission did not recurse in the
    iterator specification or loop parameter specification of quantified
    expressions, resulting in missing coverage obligations for nested
    decisions. This change fixes this by traversing all the attributes
    of quantified expressions nodes.

            * par_sco.adb (Process_Decisions): Traverse all attributes of
            quantified expressions nodes.
