* tree-chrec.c (evolution_function_is_affine_multivariate_p):
Add loopno argument. Use evolution_function_is_invariant_rec_p
instead of evolution_function_is_constant_p.
Update calls to evolution_function_is_affine_multivariate_p.
* tree-chrec.h (evolution_function_is_affine_multivariate_p):
Add loopno argument.
* tree-scalar-evolution.c (gather_chrec_stats): Call
evolution_function_is_affine_multivariate_p with a loop
number of 0.
* tree-data-ref.c (analyze_miv_subscript): Likewise.
(analyze_overlapping_iterations): Likewise.
(access_functions_are_affine_or_constant_p):
Likewise.
(build_classic_dist_vector_1): If the access functions
are equal, don't do anything.
