Fix PR tree-optimization/17672
Fix PR tree-optimization/18168
* lambda-code.c (lambda_lattice_compute_base): Fix reversed
assert test.
(gcc_tree_to_linear_expression): Add extra to existing constant.
(depth_of_nest): Factor out function used in various places.
(gcc_loop_to_lambda_loop): Clean up code a little bit. No
functional changes.
(find_induction_var_from_exit_cond): Stop guessing, and just
get the right answer :).
(gcc_loopnest_to_lambda_loopnest): Remove useless pre-allocation.
Print out message about result of attempt to create perfect nest.
(lbv_to_gcc_expression): Add type argument, use it to do math
and induction variable creation.
(lle_to_gcc_expression): Ditto.
(lambda_loopnest_to_gcc_loopnest): Create new iv with same type as
oldiv. Pass type argument to lle_to_gcc_expression and
lbv_to_gcc_expression.
Reset number of iterations after transformation.
(perfect_nestify): Remove useless pre-allocation, and cleanup
a small amount.
* tree-data-ref.c (build_classic_dist_vector): Return false for
dependences completely outside of the loop nest we asked about.
(build_classic_dir_vector): Ditto.
(compute_data_dependences_for_loop): Only add dependence relations
inside the loop we asked about.
* tree-loop-linear.c (linear_transform_loops): Use DDR_SIZE_VECT.
Compute immediate uses.
* tree-optimize.c: Move linear_transform_loops to before ivcanon.
