Akin the `py_binary` rules for `lit`, these are scoped to binaries, rather than exposing the library - binary split. The latter is available to the package (pip package) users. Tested: ``` cd utils/bazel bazel build @llvm-project//llvm:extract_ir bazel-bin/external/llvm-project/llvm/extract_ir --help ``` ...and observed expected output (rather than import not found errors) (Same for the other 2 targets).
