Fix continuation marking, and some tests.

Browse source 
* libguile/continuations.c (continuation_mark): Mark the vm
  continuations.

* libguile/vm.c (vm_cont_mark): Fix the marking function.
  (vm_mark): Fix this one too -- the size is a number of STACKITEMS,
  which we foolishly assume are the same size as SCM.

* test-suite/tests/ftw.test: Make our stat hacks verifyable without
  assuming that they are interpreted.

* test-suite/tests/r5rs_pitfall.test: Re-indent.
