5.2% regression in xr.browsing.static at 557609:557719

Project Member Reported by mthiesse@chromium.org, May 29 2018

Issue description

Looks like a v8 memory regression, no obvious VR-related CLs.

Getting build issues with third_party/guava/lib/guava.jar missing when trying to bisect this.
Tuns out it was a local issue, not tied to a revision range. Culprit roll is https://chromium-review.googlesource.com/1053874 - I'll get a specific V8 CL in a bit.
I don't know that it's worth bothering. That's a 1.8KB delta, which is effectively nothing :P
Status: WontFix (was: Untriaged)
Culprit CL is https://chromium-review.googlesource.com/1049611. Judging by the description, this is a completely expected change since it moves more stuff into the read-only space.
