intel: Only do BO caching up to 64MB objects.
This avoids making objects significantly bigger than they would be otherwise, which would result in some failing at binding to the GTT. Found from firefox hanging on: http://upload.wikimedia.org/wikipedia/commons/b/b7/Singapore_port_panorama.jpg due to a software fallback trying to do a GTT-mapped copy between two 73MB BOs that were instead each 128MB, and failing because both couldn't fit simultaneously. The cost here is that we get no opportunity to cache these objects and avoid the mapping. But since the objects are a significant percentage of the aperture size, each mapped access is likely having to fault and rebind the object most of the time anyway. Bug #20152 (2/3)
