tree-vectorizer.c (new_loop_vec_info): Initialize new field.
gcc/ChangeLog
* tree-vectorizer.c (new_loop_vec_info): Initialize new
field.
(destroy_loop_vec_info): Add call to VEC_free.
* tree-vectorizer.h (may_alias_ddrs): Define.

(vect_analyze_data_ref_dependences) Add call to
vect_mark_for_runtime_alias_test.
(vect_enhance_data_refs_alignment): Define local variable
vect_versioning_for_alias_required, don't perform
peeling for alignment if versioning for alias is
required.
(vect_enhance_data_refs_alignment): Use
PARAM_VECT_MAX_VERSION_FOR_ALIGNMENT_CHECKS instead of
PARAM_VECT_MAX_VERSION_CHECKS.
