PR tree-opt/18536
* tree-vectorizer.c (make_loop_iterate_ntimes): Use type of niters when
creating iv instead of integer_type.
(vect_build_loop_niters): Remove redundant code.
(vect_transform_loop_bound): Removed (duplicates functionality of
make_loop_iterate_ntimes.
(vect_gen_niters_for_prolog_loop): Add documentation. Call
lang_hooks.types.type_for_size to create a type of the required size.
Use that type instead of integer_type. Remove redundant code.
(vect_update_niters_after_peeling): Use type of niters instead of
integer_type.
(vect_transform_loop): Unify handling of known and unknown loop bound
cases. Call make_loop_iterate_ntimes instead of
vect_transform_loop_bound.
