Simplified testcase:
/* { dg-do compile } */
/* { dg-options -g -O -ftree-loop-distribution -fgraphite-identity } */

int
foo (int *x)
{
  int a[10], b[10];
  int i;
  a[9] = 8;
  b[9] = 8;
  for (i = 0; i  9; i++)
{
  a[i] = *x++;
  b[i] = 1;
}
  b[i] = b[i]  !(a[i] ^ *x++);
  return b[i] ? i + 1 : 0;
}

This testcase does work on the Graphite branch 
where I did not merged changes from trunk from the time when 
VTA was merged to trunk.  See PR41401 as well.
