improve construction of the original schedule

The patch builds the original schedule based on the now optimized scattering
dimension instead of building one based on the loop index only.

The implementation is simpler and catches more cases where the original schedule
and the transformed schedule are the same, such as the one below:

for (i = 0; i < 1000; i++)
{
  Temp = F[i];
  for (j = 0; j < 1000; j++)
 {
    D[j] = E[j]  * Temp;
    A[i][j] = A[i][j]  + B[i][j] * C[i][j] - D[j] ;
  }
  D[i] = E[i] * F[i];
}

  * graphite-sese-to-poly.c (build_scop_original_schedule): Call
  isl_union_map_add_map on every pbb->schedule.

Workaround PR68256 on AArch64

> This is causing a bootstrap comparison failure in gcc/go/gogo.o.

I've had a look at this and the trigger is the
aarch64_use_constant_blocks_p change which appears to be causing a
bootstrap comparison failure because of differences to offsets when
built with debug and without debug. I don't think the problem is
specifically in the backend but this needs some careful
investigation. For now, in the interest of go bootstraps continuing on
trunk - I'm proposing a patch that partially rolls back the change in
aarch64_use_constant_blocks_p and am still looking into the issue but
it will take me some more time to get to the bottom of the issue.

Bootstrapped on aarch64-none-linux-gnu including (c,c++ and go) -
testing finished ok.
