Blender was crashing with a SIGFPE even though the divide by 0
logic was kicking in. I'm not sure why TGSI doesn't get into this state.
The problem was is the numerator was INT_MIN we'd replace the div by
0 with a divide by -1, which is an exception for INT_MIN as INT_MIN/-1
== INT_MAX + 1 (too large for 32-bits). Instead for integer divides
just replace the mask values with 0x7fffffff. Also fix up the
result handling so it aligns with TGSI usage. (gives 0)

Even though the workaround description says:
"all the listed commands are non-pipelined and hence flush caused due
to pipeline mode change must not cause performance issues..."
My understanding is that we still need to have the flushes. Also, the
flushes are required not only to stall the pipeline, but also to clear
caches, so I don't think they can simply be discarded.
Additionally, while doing some testing that increased the number of
surface STATE_BASE_ADDRESS emitted, I got a lot more GPU hangs. Adding
these flushes fixes those hangs.

We are able to run only 1/5th of the tests in around the same time that
dEQP-GLES2 takes, so do that for now while more DUTs are installed.

Because we set the needs_data_cache bit from the NIR during compilation,
any time a shader was pulled out of the pipeline cache, we wouldn't set
the bit and the data cache was disabled. Fortunately, on Gen8+, this
bit is ignored because we always use the ALL section in the L3$ config
instead of separate DC and RO sections. On Gen7, however, this meant
that we were basically never running with the data cache enabled and our
compute performance was suffering massively because of it. This commit
improves Geekbench 5 scores on my Haswell GT3 by roughly 330% (no,
that's not a typo).
