--- Comment #3 from Arseny Solokha <asolokha at gmx dot com> ---
And the following one ICEs gcc-6.0.0-alpha20160221 w/ -O2 -floop-nest-optimize
-ftree-loop-distribution (note the changed set of Graphite flags):

int ff;
int wz[1], pf[1];

void
im(int lp)
{
  while (lp < 1) {
    pf[lp] = (ff < 0 || (1 << ff) == 0) ? : ff;
    wz[lp] = 0;
    ++lp;
  }
}

% x86_64-pc-linux-gnu-gcc-6.0.0-alpha20160221 -c -O2 -floop-nest-optimize
-ftree-loop-distribution vjqptgkc.c                                             
vjqptgkc.c: In function 'im':
vjqptgkc.c:5:1: internal compiler error: in bb_contains_loop_phi_nodes, at
graphite-isl-ast-to-gimple.c:1077

I'm not sure whether this one is related to the initial issue or not.
