[PATCH] D43876: [LoopUnroll] Peel off iterations if it makes conditions true/false.

Hopefully, below C code should show the case I'm pursuing. In this loop, we know that the condition is false only in the last one iteration.

void test (int* p, int* p2, int* p3, int v, int L) {

  unsigned int M = *p;
  int k;
  for (k = 1; k <= M; k++) {
    p2[k] = v;
    if (k < M) {
        p3[k] = v;
    }
  }

}
