Bisect between 12.0.3 and master to find the patch which fixed the hangs

Annoyingly, the fix is apparently:

commit 1eef0b73aa323d94d5a080cd1efa81ccacdbd0d2
Author: Kenneth Graunke <kenneth at whitecape.org>

    i965: Rewrite FS input handling to use the new NIR intrinsics.

which wasn't supposed to fix anything, but changes a lot of fragment shaders.

I suppose that tells us that it's a fragment shader that is hanging the GPU,
which is at least something to go on...
