compiler/rust: Fix the DFS loop detection algorithm
The previous algorithm just looked at the dominator's loop header.
However, if you have multiple consecutive loops like:

    function_impl {
        loop {
            // Stuff
        }
        loop {
            // Other stuff
        }
    }

then it will look like the second loop is contained in the first loop
because the first loop's header dominates the second loop.  This isn't
actually what we want.  Instead, we want a node N to be considered part
of a loop with header H if H dominates N and H is reachable from N.

Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://docs.mesa3d.org/install.html>`_), but the recommended way is to use

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install
