Blender crash dump

On Ubuntu 17.04 with a AMD Radeon R9 380 (Tonga Pro chipset), daily Mesa from
Padoka PPA (version 1:17.3~git170731230100.df61a05~z~padoka0), both Blender
2.78 and 2.79 daily build (09eac0159db) crash when the OpenCL kernel is
compiled for GPU rendering.


Steps to reproduce:
1. Start Blender with `CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 ./blender` due to
missing detection of OpenCL support (probably due to #101594).
2. Under Render settings, switch `Device` to `GPU Compute` and assert this
setting is actually used.
3. Start a render and assert the OpenCL kernel is compiled.

Actual behavior:
* Blender crashes during kernel compilation (crash dump of 2.79 build is
attached).

Expected behavior:
* Blender renders with OpenCL.

Addtional info:
* `clinfo` and `glxinfo` output is attached as well.
