OOFs and the initial column balancing pass

We lay out the OOFs during the initial column balancing pass once they
reach the CB rather than the fragmentation context root. As a result,
we may get different results in a non-initial column balancing pass.

Thus, miss the cache if the initial column balancing pass between the
new and old constraint spaces are different, and there is an OOF in
the fragmentainer subtree.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
