Glitched car windows

The game Life Is Strange has various rendering glitches with current mesa
master.

I have recorded an apitrace of the game:
 http:=
//constexpr.org/tmp/LifeIsStrange-radeonsi.trace.xz (124 MiB)

The trace contains garbage geometry that is not there in the game (probably=
 due
to persistent coherent mappings - the game crashes with
MESA_EXTENSION_OVERRIDE=3D-GL_ARB_buffer_storage), but the glitched car win=
dows
seen in the screenshot are visible. I've tracked the origin of the glitches=
 to
e.g. draw call 4741838.

All of the glitches go away when reverting commit 74e39de "radeonsi: s=
et
IF_THRESHOLD to 3" while https://patchwork.freedesktop.org/patch/122101/ does
not help, so this is likely related to bug #98761.

GPU: R9 380X (tonga)
Kernel: 4.8.7-gentoo
