Timothy Arceri 0f1cbcd6a7 gallivm: disable GLSL IR loop unrolling in LLVMPIPE
The NIR unroller is already enabled so just allow it to do its job.

We add a new failure here because llvmpipe fails to handle a
shader that is no longer unrolled.

Previously GLSL IR could unroll the loop because it only had a
single break. However once lower_returns passes over the shader
it ends up with more than 2 breaks making it no longer possible
to unroll. This is a disadvantage of doing the unrolling in NIR
however in practice we don't see shaders in the wild with multiple
returns inside loops.

Being unable to handle this loop is an existing bug with llvmpipe
exposed by the loop no longer being unrolled.

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

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.
