optimize access to arrays of rank 1 or 2
* libguile/array-handle.c (scm_array_handle_pos_1): (scm_array_handle_pos_2): New functions. * libguile/generalized-arrays.c (scm_c_array_ref_1, scm_c_array_ref_2): (scm_c_array_set_1_x, scm_c_array_set_2_x): New functions. (scm_i_array_ref, scm_i_array_set_x): New subr bindings for array-ref and array-set! that avoid consing for arrays of rank 1 or 2. * test-suite/tests/arrays.test ("array-set!"): Fix expected exception for wrong number of indices.
