Restructure the NestedSet usage in CcCompilationContext. Goals:
- Don't use NestedSets of NestedSets. Not sure whether this is a performance
  improvement or has serialization benefits, but it does make understanding the
  structure a lot easier.
- Use the same large NestedSet for all header information (whether or not they
  are modular and what pregrepped headers might exist). This speeds up the
  include scanner calls getLegalGeneratedScannerFileMap and getModularHeaders
  because they now iterate over just a single NestedSet and the second
  evaluation of a NestedSet is much cheaper. In a subsequent change, we can
  likely fold all three iterations over this NestedSet into one (in
  getLegalGeneratedScannerFileMap, getModularHeaders and getUsedModules).

Measurements show a small reduction in heap usage.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
