Revert of Roll clang 277962:278861

Revert of Roll clang 277962:278861 (patchset #6 id:100001 of https://codereview.chromium.org/2241413003/ )

Reason for revert:
This broke the build on a certain Mac builder:
https://build.chromium.org/p/chromium/builders/Mac/builds/18669

It looks like the build is timing out maybe? All other Mac
builders seem happy though, which makes this confusing, but
the buildbot logs very clearly implicate the roll: the same
kind of error happened last time it landed, and it went away
on the previous revert.
