[PATCH] Fix gcc.dg/vect/no-section-anchors-vect-64.c (PR testsuite/45429)

[Jakub Jelinek]

Hi!

This testcase expects peeling to be done in 2 loops to ensure proper
alignment.  As ia64 uses vectorization factor 2, the earlier change
from
int id[N][N][N];
to
int id[N][N][N+1];
made the 3rd loop:
  /* Multidimensional array. Not aligned: vectorizable. */
  for (i = 0; i < N; i++)
    {
      for (j = 0; j < N; j++)
        {
           id[i][1][j+1] = ib[i];
        }
    }
actually sufficiently aligned on ia64.
This patch changes it so that it is not aligned anywhere.

Ok for trunk?
