A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/2315473002/ by jgruber@chromium.org.

The reason for reverting is: Performance regressions: crbug.com/644087
Clusterfuzz: crbug.com/644074

We'll reland all regexp changes at once when the port is complete and at least
performance-neutral, since the partial port requires slow workarounds..
