Relax assumptions made in the precise VM stack marking procedure.

* libguile/vm.c (vm_stack_mark): Change assertions into checks to
  determine whether VM points to a sane (initialized) object.  The
  assumption previously was that free-list elements would be zeroed, as
  implied by the comment in <gc/gc_mark.h>, but this doesn't appear to
  be the case.
