[PATCH] D38725: [LoopUnroll] Clean up remarks for unroll remainder

[Dave Green via Phabricator via llvm-commits]

The optimisation remarks for loop unrolling with an unrolled remainder looks something like:

  test.c:7:18: remark: completely unrolled loop with 3 iterations [-Rpass=loop-unroll]
              C[i] += A[i*N+j];
                   ^
  test.c:6:9: remark: unrolled loop by a factor of 4 with run-time trip count [-Rpass=loop-unroll]
          for(int j = 0; j < N; j++)
          ^

This removes the first of the two messages.
