Elena Demikhovsky 4c58b2761a Fixed consecutive memory access detection in Loop Vectorizer. 
It did not handle correctly cases without GEP.

The following loop wasn't vectorized:

for (int i=0; i<len; i++)

  *to++ = *from++;

I use getPtrStride() to find Stride for memory access and return 0 is the Stride is not 1 or -1.
