[Bug tree-optimization/36281] New: vectorized code not parallelized

["spop at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The testcase of PR36181 should be parallelized after being vectorized.

/* { dg-do compile } */
/* { dg-options "-O3 -ftree-parallelize-loops=2" } */

int foo ()
{
  int i, sum = 0, data[1024];

  for(i = 0; i<1024; i++)
    sum += data[i];

  return sum;
}

The fix for PR36181 was to disable the parallelization of a loop when
one of the phi nodes had a vector type.  This testcase should also be
parallelized.  See also the comments from the fix for PR36181:
