Ok.

Hi All,
Here is updated patch containing missed change in
slpeel_tree_peel_loop_to_edge which prevents renaming of exit PHI uses
in inner loop.

Richard,
I attached updated patch.
You asked me to explain why I did changes for renaming.
If we do not change PHI arguments for inner loop header we can get the
following IR:
source outer loop:
: outer-loop header
# i_45 = PHI <0(4), i_18(9)>
# .MEM_17 = PHI <.MEM_4(D)(4), .MEM_44(9)>

Thanks a lot Richard for your review.
I presented updated patch which is not gated by force_vectorize.
I added test on outer-loop in vect_enhance_data_refs_alignment
and it returns false for it because we can not improve dr alighment
through outer-loop peeling in general. So I assume that only

Hi All,
Here is a simple fix which allows duplication of outer loops to
perform peeling for number of iterations if outer loop is marked with
pragma omp simd.
Bootstrap and regression testing did not show any new failures.
Is it OK for trunk?
