[Shubham Narlawar via Phabricator via llvm-commits]

Address review comments.

Run -instnamer on lit tests.

TODO - Add a negative test for the constant memory case.

I am thinking on what changes needs to be done on below testcase to become it as negative test -

int u, v;

void f(int a[restrict], int b[restrict], int n) {

  for (int i = 0; i < n; ++i) {
      if (a[i]) {
          ++u;
          break;
      }
      ++u;
      if (b[i])
          ++v;
  }

}
