Revert 159668 - This broke the reference page cyclers

Original description:
Page cyclers: output memory histograms (approach: expose JS object)

This CL makes the chrome browser expose a JS object for retrieving histograms if a command line flag is passed. Page cycler then gets the histograms by executing JS via the test automation API.

BUG=145352
