Amber test that exposes the problem

Doing:

amber -d killer.amber

causes my machine to lock up (the display freezes, then goes into a pretty cool and crazy scramble of colours).

Build: Mesa 19.2.0-devel (git-2eace10c62) (Debug)
Device: Radeon RX Vega

I expect this is related to https://bugs.freedesktop.org/show_bug.cgi?id=111147 - that was a highly reduced shader.  I have included the unreduced shader in the hope that the issue is less likely to be sensitive to small changes in shader compilation.

I have tried enabling amdgpu.gpu_recovery=1 but this doesn't seem to help.
