Move histograms and supporting code that don't belong in content out.

This CL was originally based on top of r205149 (Fast Tab Closure) and committed as r207181.  The Fast Tab Closure CL was backed out together with the previous version of this CL.

Here's another shot, doing the same cleanup as before but with r205149 reverted.
