<pre>This test began asserting with mesa 1db37ebecf5af55215ace3801f8dbb8b10c5305e
i965: Assert that the scratch spaces are in range.
I don't know that anything actually guarantees this, but if we exceed
the limits, we may end up overflowing and trashing random buffers that
happen to be nearby in the VMA space, leading to rendering corruption,
hangs, or worse.
We should really fix this properly. However, the pitfall has existed
for ages, so for now we should at least detect it.

/home/jenkins/workspace/Leeroy/repos/mesa/src/mesa/drivers/dri/i965/brw_fs.cpp:6005:
void fs_visitor::allocate_registers(bool): Assertion `prog_data->total_scratch
< 12 * 1024' failed.
IVBGT1 is not tested for developer branches in CI, so there was no way to catch
this pre-commit.</pre>
