    R mlir/lib/Bindings/Python/unix_version.lds
    M mlir/test/lit.cfg.py

  Log Message:
  -----------
  [mlir] Make Python bindings installable.

* Links against libMLIR.so if the project is built for DYLIBs.
* Puts things in the right place in build and install time python/ trees so that RPaths line up.
* Adds install actions to install both the extension and sources.
* Copies py source files to the build directory to match (consistent layout between build/install time and one place to point a PYTHONPATH for tests and interactive use).
* Finally, "import mlir" from an installed LLVM just works.
