/* CELL_P checks a random word whether it has the right form for a
pointer to a cell. Use scm_i_find_heap_segment_containing_object
to find out whether it actually points to a real cell.
The right form for a cell pointer is this: the low three bits must
be scm_tc3_cons, and when the scm_tc3_cons tag is stripped, the
resulting pointer must be correctly aligned.
scm_i_initialize_heap_segment_data guarantees that the test below
works.
