List clean build fences. Every line should include a reference to a bug which justifies the
addition.

WARNING: Exercise great caution when adding to this file, as the consequences are
significant and widespread. Every Fuchsia developer and builder will have their incremental
build cache invalidated when receiving or reverting the change to do so. Only add to this
file after consulting with the Build team about failed attempts to address build convergence
issues within the dependency graph.
