As long as we have a tc7 for arrays, we should be able to access it with
a struct type instead of casting each word.
* libguile/arrays-internal.h: New file.
* libguile/arrays.h (scm_array_p): Take just one argument.
(SCM_I_ARRAYP):
(SCM_I_ARRAY_NDIM):
(SCM_I_ARRAY_V):
(SCM_I_ARRAY_BASE):
(SCM_I_ARRAY_DIMS):
(SCM_I_ARRAY_SET_V):
(SCM_I_ARRAY_SET_BASE): Remove.
(scm_i_raw_array, scm_i_make_array, scm_i_shap2ra, scm_init_arrays):
Remove internally-linked decls.
* libguile/init.c:
* libguile/print.c:
* libguile/array-handle.c: Use interfaces from new file.
* module/system/vm/assembler.scm: Update, as we now shift the dimension
count by only 16. Requires a rebuild!
