allocation_point Variable.Map.tSimple alias analysis working over information about which symbols have been assigned to variables; and which constants have been assigned to symbols. The return value gives the assignment of the defining values of constants to variables. Also see comments for Lift_constants, whose input feeds this pass.
Variables found to be ill-typed accesses to other constants, for example arising from dead code, will be pointed at the_dead_constant.
