Comment # 3 on bug 93352 from Ilia Mirkin

The first issue is somewhere with glsl ir -> tgsi translation of a tessellation
evaluation program. The second issue is that the generated TGSI is somehow
problematic (or radeonsi has issues processing it).

It might be helpful to run the program with

MESA_GLSL=dump ST_DEBUG=tgsi

in the environment, and provide the resulting log file. I expect it'll be quite
large.
