Reland of land Compile under-invalidation checking in all builds (patchset #2 id:300001 of https://codereview.chromium.org/2309193002/ )
Reason for revert:
This should be landed to discover under-invalidations. If any test hit this, we should mark the test fail instead of reverting this.
The failed test had been marked failure before the revert.
