* tree-data-refs.h (split_constant_offset): Add declaration.
* tree-vectorizer.h (dr_alignment_support): Renamed
dr_unaligned_software_pipeline to dr_explicit_realign_optimized.
Added a new value dr_explicit_realign.
(_stmt_vec_info): Added new fields: dr_base_address, dr_init,
dr_offset, dr_step, and dr_aligned_to, along with new access
functions for these fields: STMT_VINFO_DR_BASE_ADDRESS,
STMT_VINFO_DR_INIT, STMT_VINFO_DR_OFFSET, STMT_VINFO_DR_STEP, and
STMT_VINFO_DR_ALIGNED_TO.
* tree-vectorizer.c (vect_supportable_dr_alignment): Add
documentation.
In case of outer-loop vectorization with non-fixed misalignment - use
the dr_explicit_realign scheme instead of the optimized realignment
scheme.
(new_stmt_vec_info): Initialize new fields.
* tree-vect-analyze.c (vect_compute_data_ref_alignment): Handle the
'nested_in_vect_loop' case. Change verbosity level.
(vect_analyze_data_ref_access): Handle the 'nested_in_vect_loop' case.
Don't fail on zero step in the outer-loop for loads.

offset and init relative to the outer-loop.
* tree-vect-transform.c (vect_create_data_ref_ptr): Replace the unused
BSI function argument with a new function argument - at_loop.
Simplify the condition that determines STEP. Takes additional argument
INV_P. Support outer-loop vectorization (handle the nested_in_vect_loop
case), including zero step in the outer-loop. Call
vect_create_addr_base_for_vector_ref with additional argument.
(vect_create_addr_base_for_vector_ref): Takes additional argument LOOP.
Updated function documentation. Handle the 'nested_in_vect_loop' case.
Fixed and simplified calculation of step.
(vectorizable_store): Call vect_create_data_ref_ptr with loop instead
of bsi, and with additional argument. Call bump_vector_ptr with
additional argument. Fix typos. Handle the 'nested_in_vect_loop' case.
(vect_setup_realignment): Takes additional arguments INIT_ADDR and
DR_ALIGNMENT_SUPPORT. Returns another value AT_LOOP. Handle the case
when the realignment setup needs to take place inside the loop. Support
the dr_explicit_realign scheme. Allow generating the optimized
realignment scheme for outer-loop vectorization. Added documentation.
(vectorizable_load): Support the dr_explicit_realign scheme. Handle the
'nested_in_vect_loop' case, including loads that are invariant in the
outer-loop and the realignment schemes. Handle the case when the
realignment setup needs to take place inside the loop. Call
vect_setup_realignment with additional arguments. Call
vect_create_data_ref_ptr with additional argument and with loop instead
of bsi. Fix 80-column overflow. Fix typos. Rename PHI_STMT to PHI.

vect_create_addr_base_for_vector_ref with additional arguments.
(vect_create_cond_for_align_checks): Likewise.
(bump_vector_ptr): Updated to support the new dr_explicit_realign
scheme: takes additional argument bump; argument ptr_incr is now
optional; updated documentation.
(vect_init_vector): Takes additional argument (bsi). Use it, if
available, to insert the vector initialization.
(get_initial_def_for_induction): Pass additional argument in call to
vect_init_vector.
