fix busted JavaScript in error index generator

Browse source 
The old JavaScript didn't work. It filled the browser console
with "e.previousElementSibling not defined" errors, because
it didn't account for the example-wrap div that a newer version
of rustdoc added.

Additionally, it had copied versions of utility functions that
had been optimized in rustdoc main.js. This version updates those.
