Ok, I just (re-)discovered that this is a non-issue: these encoding
changes are done by SCM2PTR and PTR2SCM.

Right now, I have a version of Guile that doesn't store scm_t_bits
into the heap, and it does feel a cleaner since no scm_t_bits* <->
SCM* casts are done.

Now, I'll try to completely remove the use of the scm_t_cell type
(only the use, not the definition).  This one is rather confusing as
well since it is not used consequently (I think).
