squirrely smob marking refactor
* libguile/smob.c (smob_mark): No idea what the right thing is to do
here.

redo the SCM tagging strategy
Currently failing some guardian tests.
* libguile/tags.h: Refactor tagging so that tc3 bits for a pair live in
the SCM value, not in the heap words. Do the same for structs. This
more rational tagging strategy will make native code generation
easier. Note that this means that to check a heap pointer for its
type, you first have to ensure that it has the expected tc3, as not
all the type bits are on the heap.
(SCM_TYP3): Check the SCM tag type, not the bits in the cell.
(SCM_HAS_TYP3): New helper.
(SCM_I_CONSP): Redefine to just check the typ3.
(scm_tcs_cons_imcar, scm_tcs_cons_nimcar, scm_tcs_struct): Remove, as
they are no longer necessary.
* libguile/array-handle.c (scm_i_array_implementation_for_obj): Check
for heap objects before checking type bits, so we don't check pairs.
* libguile/evalext.c (scm_self_evaluating_p):
* libguile/gc.c (scm_i_tag_name):
* libguile/goops.c (scm_class_of)
* libguile/hash.c (scm_hasher):
* libguile/print.c (iprin1): Adapt to tagging changes.
* libguile/gc.c (scm_storage_prehistory): Register all displacements
here. There are the same displacements as before, unfortunately.
* libguile/inline.h (scm_is_pair): Remove the (crufty!) GCC workaround,
as we no longer check the heap to see if something is a pair.
* libguile/list.c (SCM_I_CONS):
* libguile/pairs.c (scm_cons):
* libguile/vm-engine.h (CONS): Tag pairs with scm_tc3_pair.
* libguile/modules.c (scm_post_boot_init_modules):
* libguile/modules.h (SCM_MODULEP):
* libguile/struct.c (struct_finalizer_trampoline, scm_i_alloc_struct):
(scm_make_vtable_vtable):
* libguile/struct.h (SCM_STRUCTP, SCM_STRUCT_VTABLE_DATA):
(SCM_STRUCT_VTABLE_SLOTS):
* libguile/vm-i-scheme.c (make-struct): Adapt to struct tagging
changes.
* libguile/numbers.h (SCM_I_INUMP):
* module/rnrs/arithmetic/fixnums.scm (fixnum?, inline-fixnum?): Adapt
to the new fixnum tag.
* libguile/numbers.h (SCM_INEXACTP): Make sure of the tc3 before looking
at the cell type.

add SCM_HEAP_OBJECT_BASE
* libguile/tags.h (SCM_HEAP_OBJECT_BASE): New macro. Given a SCM,
returns a pointer to the start of its memory area on the heap.
