* tree-vectorizer.h (struct _stmt_vec_info): Add new field to
determine if the statement is vectorizable, and a macro to
access it.
* tree-vect-data-refs.c (vect_analyze_data_ref_dependence):
Skip statements that can't be vectorized. If the analysis
fails, mark the statement as unvectorizable if vectorizing
basic block.
(vect_compute_data_refs_alignment): Likewise.
(vect_verify_datarefs_alignment): Skip statements marked as
unvectorizable. Add print.
(vect_analyze_group_access): Skip statements that can't be
vectorized. If the analysis fails, mark the statement as
unvectorizable if vectorizing basic block.
(vect_analyze_data_ref_accesses, vect_analyze_data_refs):
Likewise.
* tree-vect-stmts.c (vectorizable_store): Fix the number of
generated stmts for SLP.
(new_stmt_vec_info): Initialize the new field.
* tree-vect-slp.c (vect_build_slp_tree): Fail to vectorize
statements marked as unvectorizable.
