Variable names may be changed accidentally

Source code

#pragma scop
for (int i = 0; i < N; i++)
  a_i_k[i] = 0;
#pragma endscop

raised to the model by Clan and regenerated by CLooG is transformed to

#pragma scop
  /* Scattering iterators. */
  int i;
if (N >= 1) {
  for (i=0;i<=N-1;i++) {
    a_(i)_k[i] = 0;
  }
}
#pragma endscop

The i symbol in the variable name is being processed as if it were iterator.

Funny :-) ! This is a problem in OpenScop's osl_util_identifier_is_here function. I (shamefully) forgot the underscore case...

I fixed it in https://github.com/periscop/openscop/commit/3f557dc265ee6f2545c92f11091e2bfbd1656dfb.

Do not forget to update osl submodule version for the next ClooG release.
