Summary

Remove the window.performance.webkit* functions.

Motivation

It has been deprecated as PrefixedUserTiming since April 2013 (r148849).

Usage information from UseCounter

This was on pdr's list <http://crbug.com/332191> of features which are "unused or have extremely low usage numbers". The use counter is old enough to have been in the stable channel for a while now.

Compatibility Risk

Scripts that use only the prefixed methods will start throwing exceptions.

Row on feature dashboard?
