Ian Romanick 598e2fc6a1 soft-fp64: Pick a single idiom for treating sign value as a Boolean
Replace all of the bool(qSign) with qSign != 0u.  Remove unnecessary
parenthesis from around most of the existing qSign != 0u.

This dramatically simplifies the next commit.

Results on the 308 shaders extracted from the fp64 portion of the OpenGL
CTS:

Tiger Lake and Ice Lake had similar results. (Tiger Lake shown)
total instructions in shared programs: 848109 -> 848106 (<.01%)
instructions in affected programs: 53 -> 50 (-5.66%)
helped: 1
HURT: 0

total cycles in shared programs: 6969145 -> 6969125 (<.01%)
cycles in affected programs: 396 -> 376 (-5.05%)

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

.. 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
