shell toolchain: genrule now uses it genrule() now uses the shell toolchain (as well as the ShellConfiguration config fragment) to look up the shell interpreter's path. Also the CommandHelper no longer looks up the shell interpreter's path itself. Instead its ctor takes the path as an argument. This allows supporting rules that already use the shell toolchain and rules that still only consider the configuration fragment. With these changes genrule() is now able to use the shell interpreter registered as a toolchain, even if there's no `--shell_executable` flag specified (or its value is empty). Subsequent commits will migrate more and more rules to depend on the shell toolchain. This commit takes us closer to: 1. be able to detect the local shell interpreter's location, especially when it's not the default /bin/bash 2. be able to define different shell toolchains (different interpreter paths) for remote builds 3. gracefully fail the build if the machine has no shell installed but the action graph included a shell action See https://github.com/bazelbuild/bazel/issues/4319 Change-Id: I0674c7e2d5917643d87b48b19a1cb43e606ad2f7 Closes #5282.

{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.
