Andre ff you use yaourt grab pkgs by: yaourt -G mesa-git and yaourt -G
lib32-mesa-git, and make it and install (cd mesa-git; makepkg -si; and the same
for lib32-mesa-git)
CS GO is 32bit (i belive) app so you need bisect only lib32-mesa-git:
Try commit:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=ef7e0b39a24966526b102643523feac765771842
It's first one I can build against llvm-3.6, it's probably old enough to run
CS:GO without issues but you have to be sure:

$cd lib32-mesa-git 
$cd src/mesa
$git checkout ef7e0b39a24966526b102643523feac765771842
$cd ../..
$makepkg -efsi
//Try CS:GO and if it's ok, let's bisect:
$cd src/mesa
$git bisect start 
//git bisect good _commit_when_CSGO_ok
$git bisect good ef7e0b39a24966526b102643523feac765771842
//git bisect bad _commit_when_you_see_issue
//you may use mesa 10.5.1 release note:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=11c0ff60ef19cca84452aa989fb8bb25127473e0
$git bisect bad 11c0ff60ef19cca84452aa989fb8bb25127473e0
//now you can see info about need check some commit
$cd ../..
$makepkg -efsi  
//and now try CS:GO
//if CS GO has issues still
$cd src/mesa
$git bisect bad
//or if CS GO runs without issues
$cd src/mesa
$git bisect good 
-->GOTO //now you can see info about need check some commit 

//you need check another commit again and again... and again until it gives to
you "first bad commit" and this "first bad commit" is wanted by Michel 

I hope it help a bit.
If ef7e0b39a24966526b102643523feac765771842 is bad, you need llvm-3.5 and start
from older mesa commit.
