PTAL Geoff, is it possible the completeness cache slowed down because of this change?

Fix the texture completeness cache.

Two silly mistakes were landed in 9aded1:
 * The cache was not updating the sampler state it was using to compare
   against new ones.
 * The SamplerCompletenessCache entry was being copied and not updated.
