Connor Abbott d30ff374a1 nir, glsl: Add support for softfloat32
Based on existing softfloat64 support and Berkeley SoftFloat. This is
targeted at drivers that can't preserve denorms, so operations where
denorm support is irrelevant like conversions to/from integers aren't
handled.

Because the existing mechanism used by Gallium for softfloat64 doesn't
support includes, we unfortunately can't extract common code into a
header. This can be done later if we switch Gallium to using glslang and
spirv-to-nir.

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://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

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