Revert of Reland Compile under-invalidation checking in all builds

Revert of Reland Compile under-invalidation checking in all builds (patchset #4 id:60001 of https://codereview.chromium.org/2301303002/ )

Reason for revert:
Causing failures on WebKit Mac 10.9:
https://build.chromium.org/p/chromium.webkit/builders/WebKit%20Mac10.9

updating-scrolling-container-and-content.html is hitting the new CHECK on
PaintController.cpp:662. It's not clear why this passed on build #36527; all
other builds since this landed failed.

A revert of this CL (patchset #2 id:300001) has been created in
https://codereview.chromium.org/2314103002/ by wangxianzhu@chromium.org.

The reason for reverting is: This should be landed to discover
under-invalidations. If any test hit this, we should mark the test fail instead
of reverting this.
