Samuel Iglesias Gonsálvez 0ff13c291b intel/nir: do not apply the fsin and fcos trig workarounds for consts
If we have fsin or fcos trigonometric operations with constant values
as inputs, we will multiply the result by 0.99997 in
brw_nir_apply_trig_workarounds, making the result wrong.

Adjusting the rules so they do not apply to const values we let a
later constant fold to deal with it.

v2:
- Do not early constant fold but only apply the trig workaround for
  non constants (Caio).
- Add fixes tag to commit log (Caio).

Fixes: bfd17c76c1 "i965: Port INTEL_PRECISE_TRIG=1 to NIR."

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

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.
