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.

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).

When Brian in 02c3dad0f3 restricted
the shm permissions it means we hit the fallback paths in some
scenarios we hadn't before.
When you use Xephyr to xdmcp from one user to another the new perms
stop the X server (running as user a) attaching to the SHM segments
from gnome-shell (running as user b).
In this case however only the GLX side of the code had insight into this,
and the dri could was meant of fall back, and it worked for put image
fine but the get image path was broken, since there was no indication
in the broken case of the need to fallback.
This adds a return type to a new interface member that lets the
caller know it has to fallback.

The other source of the multiply will be interpreted as a uint32_t in an
XOR instruction. Any source modifiers with either not be interpreted at
all or will be misinterpreted due to the differing types.
If the other operand of the multiplication has a source modifier, just
emit an extra move to resolve the source modifiers.
The negation source modifier problem is difficult to reproduce due to an
algebraic optimization that changes (-a*b) to -(a*b). However, changes
in MR !1359 push the negations back down.
On Gen7+ it might be possible to do slightly better for an abs() source
modifier by using BFI2 as a glorified copysign().
On Gen8+ it might be possible to do slightly better for a neg() source
modifier by emitting (~a ^ b).
There were no shader-db changes on any Intel platform, so I think we can
deal with that problem when it arises.

(cherry picked from commit 6af14d3685)
Together with the fixup_nomask_control_flow() pass introduced in a
previous patch, this implements a less invasive alternative to the
workaround documented in the hardware spec for GEN:BUG:1407528679,
which doesn't involve disabling structured control flow.
Under some conditions Gen12 hardware can end up executing a BB with
all channels disabled, which will lead to the execution of any NoMask
instructions in it, even though any execution-masked instructions will
be correctly shot down. This could break assumptions of the SWSB pass
if the data computed by a NoMask instruction is synchronized against
by using an SWSB annotation baked into a regular execution-masked
instruction, since the first (NoMask) instruction may be executed
redundantly by the hardware, even though the second will correctly be
shot down, potentially leading to a RaW or WaW hazard if a third
instruction subsequently accesses the destination register of the
first instruction.
