-- a call in this notation, it is transformed into a normal subprogram call
-- where the prefix is a parameter, and True is returned. If node N is not
-- of this form, it is unchanged, and False is returned. If CW_Test_Only is
-- true then N is an N_Selected_Component node which is part of a call to
-- an entry or procedure of a tagged concurrent type and this routine is
-- invoked to search for class-wide subprograms conflicting with the target
-- entity. If Allow_Extensions is True, then a prefixed call of a primitive
-- of a non-tagged type is allowed as if Extensions_Allowed returned True.
-- This is used to issue better error messages.
