Heap frames have a "frame kind" bit
* libguile/frames.h (enum scm_vm_frame_kind, SCM_VM_FRAME_KIND) (scm_c_make_frame): Add a "frame kind" bit to the first word. This will allow the "stack holder" to be a non-SCM object. * libguile/continuations.c (scm_i_continuation_to_frame): * libguile/frames.c (scm_c_make_frame, scm_frame_previous) * libguile/stacks.c (scm_make_stack): * libguile/vm.c (vm_dispatch_hook): Adapt frame creators to set the frame kind bit.
