Connor Abbott 969369e962 ir3/lower_subgroups: Fix potential infinite loop
I was trying to be clever here, skipping ahead to the newly-created
block and processing the remaining instructions after the split in the
same loop. But if the last instruction in a block was lowered, the saved
next instruction would be the head of the block before the split, not
the new block, and we would compare it to the new block so we wouldn't
stop like we were supposed to. Stop being so clever, and just restart
processing with the new block after lowering an instruction.

Because we're wrapping the actual transform in yet another loop, and the
restarting logic is a bit tricky, refactor the actual lowering into a
separate lower_instr function. Otherwise we'd be mixing the two and
indenting the actual logic even more.

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
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://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
