This bug goes away on rebuilding beignet with LLVM 3.8 (but that isn't a
good solution as it can trigger #848368, and also disables some of
beignet's functionality).
Debug backtraces show mesa-opencl-icd being loaded first, and the crash
happening when beignet-opencl-icd is loaded, suggesting one is jumping
to the other's LLVM globals (similar to #768185).
However, beignet still has the -Bsymbolic that fixed #768185 on all its
libraries, and while mesa-opencl-icd doesn't, adding it (via the obvious
patch to src/gallium/targets/opencl/Makefile.am) doesn't help.
(The missing parameters/locals in the LLVM parts of the traces are
probably #851371; because of this, I was unable to do the
is-this-the-same-pointer check from #768185)
