Refactor BuildingState to save memory. Collapse the "evaluating" boolean into the "signaledDeps" int field, since signaledDeps is always 0 if evaluating is false, so we can use the sentinel value -1 to indicate that evaluation has not yet started. This leads to a slightly less tolerant node entry: it must "start evaluating" before you can do things like set its value. Places that wasn't being done have been fixed, at least as far as we have test coverage for. Also, factor the "dirty" parts of BuildingState out into a subclass. It would probably be cleaner to use composition here, but I don't want to pay the price of another object. -- MOS_MIGRATED_REVID=126729331

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:
A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.
An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.
Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
