Hey Guix,

here's a patch to update Mesa on staging to the just released 18.1.1.
Since there's a little more involved than usual I'm sending it in for
review first.

The 18.1 series needs to be built with LLVM >= 4 (the current
18.2-devel series needs to be built with LLVM >=5). As such I've
changed Mesa to use LLVM 6.0.

Feedback/testing welcome!

I'm withdrawing this patch for now. I keep getting segfaults with Mesa
18.1.1.

For now I've updated Mesa in staging to 18.0.5 instead, which
is the last release of the 18.0 series. It's also the last version to
support LLVM < 4.

Under which circumstances did you get a segfault?

I'm currently running IceCat using this Mesa and will reconfigure my
system to test it further, but so far so good here.

I think it has something to do with shader compilation. It kept
segfaulting for me when I tried to start a program that seemed to use
OpenGL. This included me being unable to start SDDM/GNOME (all I got
was a black screen).

Oddly enough, programs that use Vulkan instead seemed fine.

I figured out after closing this patch that if I use another
experimental way of compiling shaders, by setting the environment
variable "R600_DEBUG=nir" it no longer crashes for me.

If it works for you after reconfiguring your entire system you can push
it to staging if you want. I'll just set the environment variable
globally then since I don't wanna hold up this Mesa upgrade.

On a side note, GNOME on Wayland's menus were broken for me starting
with Mesa 18.0+, where the menus wouldn't respond at all. Don't know if
that's still the case. If it is GNOME will probably have to be
upgraded at some point.

So it turned out that me mixing Mesa versions (I also used a git
version of Mesa for myself) confused Mesa. I solved it by deleting
~/.cache/mesa_shader_cache. 

I doubt that this will be a problem for anyone else, so here's a
new rebased patch that updates Mesa to 18.1.1. With your blessing I'll
push it to staging.
