I amanaged to build llvm and mesa.

Here's my test results:
As for both wine applications 3D Mark 2000 and Syberia, the error is gone and
both applications continue past normally.

But Antichamber will crash the system hard.
I have found place in the game where the llvm error always happens.
When I use your version of llvm 3.5 instead of llvm 3.4 Antichamber wont exit
with the error it will instead deadlock the whole system, only option is
reboot.
