Code

Fixed some bugs in the vector list re-ordering function. This should work now,

but there's another problem in the dumping code that still spoils the fun.

- inst.c (do_move_to_vec): marking algorithm propagated an uninitialized value
- inst.c (do_move_to_vec): we have to clear the marks of vectors that are 
  before the vector being moved, because they will still be visited and 
  propagated
