common.opt: Add option ftree-vect-loop-version.
* common.opt: Add option ftree-vect-loop-version.
* params.def: Add --param vect-max-version-checks.
* doc/invoke.texi: Document ftree-vect-loop-version and
--param vect-max-version-checks.
* tree-vectorizer.h (_loop_vec_info): Add ptr_mask and
may_misalign_stmts and defines for accessors.
* tree-vectorizer.c : (new_loop_vec_info): VEC_alloc for
LOOP_VINFO_MAY_MISALIGN_STMTS.
(destroy_loop_vec_info): VEC_free for
LOOP_VINFO_MAY_MISALIGN_STMTS.
* tree-vect-analyze.c (vect_compute_data_ref_alignment):
Update documentation.
(vect_update_misalignment_for_peel): New.
(vect_enhance_data_refs_alignment): Update to choose loop
peeling or loop versioning if appropriate for the (potentially)
unaligned data references in the loop.
(vect_analyze_data_refs_alignment): Remove call to
vect_enhance_data_refs_alignment so the checks can be done
earlier.
(vect_analyze_loop): Add call to vect_enhance_data_refs_alignment
and move up call to vect_analyze_data_refs_alignment.
* tree-vect-transform.c (vect_create_cond_for_align_checks): New.
(vect_transform_loop): Add call to loop_version.
