Roll build and clang.

https://chromium.googlesource.com/chromium/src/build.git/+log/67630827e138..213e0a3a3d17
https://chromium.googlesource.com/chromium/src/tools/clang/+log/2cf76f56cb0f..3a16568a5648

Roll clang 349417:351477. They have to be rolled together due to the
Clang version bumper to 9.x.

Also update UnownedPtr to make its unit tests pass when
ProbeForLowSeverityLifetimeIssue() is active.
