Always track parallelism in EvaluationContext

EvaluationContext has 2 members for different configurations it is run with
(either is set, never both):
  1. Integer numThreads -- this allows delegating the decision of what kind
  ExecutorService to create to the user
  2. Supplier<ExecutorService> executorService -- factory of ExecutorService
  objects -- makes the user tied to what it returns

Some places in the code are interested in knowing the parallelism of the
executor, which currently is achieved by assuming the kind of thread pool we
would use in case numThreads is not set.

Change the EvaluationContext to always require and store the parallelism (even
if the ExecutorService supplier is specified). Rename the getter to
'getParallelism' to avoid confusion with the old concept.

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.
