minecraft log with MESA_GLSL=dump ST_DEBUG=tgsi R600_DEBUG=vs,gs,ps

I'm seeing this too, so far only when opening a chest.

Based on this IRC snippet/log
https://people.freedesktop.org/~cbrill/dri-log/?channel=dri-devel&date=2016-04-17
I tried running it with `MESA_GLSL=dump ST_DEBUG=tgsi R600_DEBUG=vs,gs,ps` and
captured the attached.

```
$ lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710
[Radeon HD 4350/4550]
```

I'm also running Debian Sid and there does seem to be some correlation with an
`dist-upgrade` I did on 3 March.

```
