tree-vectorizer.h (struct _loop_vec_info): Add no_data_dependencies field.
* tree-vectorizer.h (struct _loop_vec_info): Add no_data_dependencies
field.
(LOOP_VINFO_NO_DATA_DEPENDENCIES): Define.
* tree-vect-data-refs.c (vect_analyze_data_ref_dependence): Clear it
when not giving up or versioning for alias only because of
loop->safelen.
(vect_analyze_data_ref_dependences): Set to true.
* tree-vect-stmts.c (hoist_defs_of_uses): Return false if def_stmt
is a GIMPLE_PHI.
(vectorizable_load): Use LOOP_VINFO_NO_DATA_DEPENDENCIES instead of
LOOP_REQUIRES_VERSIONING_FOR_ALIAS, add && !nested_in_vect_loop
to the condition.
