* tree-vectorizer.h (struct _stmt_vec_info): Add new field
read_write_dep and macros for its access.
* tree-vectorizer.c (new_stmt_vec_info): Initialize the new field.
* tree-vect-analyze.c (vect_analyze_data_ref_dependence): Remove
argument, call vect_check_interleaving for every independent pair of
data-refs. Mark loads that access the same memory location as a store
in the loop.
(vect_check_dependences): Remove.
(vect_analyze_data_ref_dependences): Remove vect_check_dependences
call, fix the call to vect_analyze_data_ref_dependence.
(vect_analyze_data_ref_access): For statements that access the same
data-ref, check that they are not stores; for loads, check that there
is no store that access the same location.
