Ian Romanick 58164794f4 spirv: Use nir_type_convert instead of nir_type_conversion_op
In a future commit, nit_type_conversion_op won't be able to handle i2b
(and in a much later commit f2b), so switch many users to the fully
featured function.

No shader-db or fossil-db changes on any Intel platform.

v2: Use the actual bit size of the source to determine the conversion
op.  With mediump, the "planned" bit size and the actual bit size might
be different.  Fixes many, many Vulkan CTS assertion failures on any
platform that sets mediump_16bit_alu (e.g., Freedreno).

======================================================


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
