Using this patch, we don't bail out immediately when graphite didn't set
loop->can_be_parallel, but try a bit harder:
...
diff --git a/gcc/tree-parloops.c b/gcc/tree-parloops.c

loop nest at parloops:
...
parloop (int N)
{
_Bool Cross_BB_scalar_dependence.11_I_lsm.23;
unsigned int Cross_BB_scalar_dependence.11_I_lsm.22;
_Bool Cross_BB_scalar_dependence.13_I_lsm.21;
