[PATCH] D38085: Use the basic cost if a GEP is not used as addressing mode

I'm okay reverting this change if the regression caused by this change is significant and prevent many people from testing their compiler. As we go back to the original cost model, we optimistically assume that a GEP will fold into addressing mode later in the pipeline.  In other words, the Free from getUserCost for a GEP is "expected to be cheap", not really free. So, don't we need to change the name from "Free" to "Cheap"?
