Chad Rosier 2588aa9425 [LIR] Add support for creating memcpys from loops with a negative stride. 
This allows us to transform the below loop into a memcpy.

void test(unsigned *__restrict__ a, unsigned *__restrict__ b) {
  for (int i = 2047; i >= 0; --i) {
    a[i] = b[i];
  }
}

This is the memcpy version of r251518, which added support for memset with
negative strided loops.
