bazel-compilation-db

Generate compile_commands.json and run clang-tidy with Bazel. This is an adaptation of Kythe's approach with a small patch to support the latest version of Bazel.

1. Append WORKSPACE to your repository's WORKSPACE file.
2. Copy third_party to your repository directory.
3. Optionally replace 'kind(cc_.*, //...)' in third_party/tools/generate_compilation_database.sh.

To generate a compile_commands.json file in $(bazel info execution_root), run third_party/tools/generate_compilation_database.sh. To use clang-tidy, run third_party/tools/clang_tidy.sh.

Tested with Bazel 0.27.0.
