sundries: side effects in interpreted repl, wrong-num-args in vm, self-checks

Browse source 
* libguile/vm-engine.c (vm_error_wrong_num_args): Sync the registers
  before calling scm_wrong_num_args. (The other cases are handled more
  uniformly.)

* libguile/vm.c (vm_heapify_frames_1): Add a FIXME: I don't think we
  should be modifying the stack.
  (scm_vm_save_stack): If stack nulling is enabled, verify the stack here
  before reifying it.

* module/language/scheme/spec.scm (scheme): Use primitive-eval here
  instead of eval, because at the repl we do want to allow evaluations to
  have side effects like setting the current module.
