guile/libguile/vm.h
Andy Wingo 6f3b0cc29e tc7 tags for vm-related data
* libguile/tags.h (scm_tc7_frame, scm_tc7_objcode, scm_tc7_vm)
  (scm_tc7_vm_cont): Take more tc7s for VM-related data structures.

* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc.c (scm_i_tag_name):
* libguile/goops.c (scm_class_of, create_standard_classes):
* libguile/print.c (iprin1): Add cases for the new tc7s.

* libguile/frames.c:
* libguile/frames.h:
* libguile/objcodes.c:
* libguile/objcodes.h:
* libguile/vm.c:
* libguile/vm.h: Desmobify.

* libguile/vm.c (scm_vm_apply): Export to Scheme, because VM objects are
  no longer applicable.

* module/system/repl/command.scm (profile):
* module/system/vm/trace.scm (vm-trace):
* module/system/vm/vm.scm (vm-load): Call vm-apply to run a program in a
  VM instead of treating the VM as applicable.
