Remove some empty structs that weren't used.  Apparently empty structs
are illegal C.

-   This is used to record if a closure has been updated but not yet

-   subsequently entered.

-   NB: It is {\em not} an ``entry count'', it is an

-   @_Evacuate@ and @_Scavenge@ code for @CONST@, @CHARLIKE@ and @INTLIKE@
-   info tables to be @_Evacuate_1@ and @_Scavenge_1_0@.
