This prevents improper later calls to
Check_Aspect_At_End_Of_Declarations, that would happen when the
constructed task_procedure body (generated during expansion) is
analyzed. The legality of aspect specifications that may appear
on local declarations has already been established, and it is in
general not possible to recheck them properly during expansion,
