This updates the Bazel toolchain logic to work on macOS. Much like on Linux, I'm not testing this against a *released* LLVM, but against a from-source build. You can build and install LLVM from top-of-tree locally with CMake, or on macOS maybe use Homebrew like: ``` brew install llvm --HEAD ``` You then need to point Bazel to the installed `clang` executable if it is not placed onto your PATH (Homebrew doesn't): ``` bazel test --repo_env=CC=$HOME/homebrew/opt/llvm/bin/clang //parser:all ``` This builds and passes tests for me at least. The fuzzer feature may not work (yet) with this setup, but that can be improved incrementally as we proceed.
