Hi thakis@chromium.org, the bisect results pointed to your CL, please take a look at the
results.


===== BISECT JOB RESULTS =====
Status: completed


===== SUSPECTED CL(s) =====
Subject : Roll clang 287780:288545.
Author  : thakis
Commit description:
  
Ran `tools/clang/scripts/upload_revision.py 288545`.

This brings in a regression for linux lld ( bug 670397 ), but nobody uses that yet.
In return, it speeds up CFI blacklist processing, makes it possible to turn on blink
PCH use on Windows (would crash previously), and makes win/asan work in
component builds again.

thakis@, Bisect results points to r436228 as possible culprit for the regression.
Could you please take a look at this?

Looks like we're not longer monitoring this metric.
