Jesse Natalie 3c8bcdc863 nir: Add a new opcode for [un]packing doubles
HLSL doesn't support bitcasting a 64bit integer to a double. DXIL
doesn't have generic pack/unpack instructions, so we lower those to
integer bitwise ops. As a result, NIR generic double pack/unpack would
require our backend to emit a bitcast to get a double, but we want
to match HLSL semantics and emit MakeDouble/SplitDouble.

Adding a dedicated opcode for double pack/unpack allows us to add a
pass to emit that instead, which lets our backend emit the right
instruction to pack and unpack doubles.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library
======================================================


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 `Freenode's #dri-devel
<irc://chat.freenode.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
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_


Bug reports
-----------
