The android extension enables the driver to blit from single-sampled
color attachments.
Adding this image usage expressess that functionality and causes anv to
generate the ISL_FORMAT_RAW-formatted clear color during fast-clears.
This fixes an assert failure when anv tries to override the clear color
format used for a blorp_blit() call to ISL_FORMAT_RAW.
There are other ways to handle this, but this solution is consistent
with our handling of multisample images (which may be resolved as well).

Android CTS CtsGpuProfilingDataTest#testProfilingDataProducersAvailable
intermittently fails with "Render stages reported before their
VkQueueSubmit events". Root cause is in the Perfetto clock correlation:
render-stage timestamps go through intel_device_info_timebase_scale()
while VkQueueSubmit packets use BOOTTIME directly, so any drift in the
scaler shows up as render stages preceding their submits.
intel_device_info_timebase_scale() scales the upper and lower halves
of the raw timestamp separately and recombines them, but silently
drops the upper-half division's remainder. When the frequency doesn't
evenly divide 1e9, every wrap past 2^32 loses a fixed number of ns
and shows up as a step in Perfetto's GPU-vs-BOOTTIME snapshot offset.
Carry the upper-half remainder into the lower-half numerator before
dividing, so no precision is lost. All intermediates still fit in
uint64_t.

Passes the ACCESS_CAN_REORDER flag from NIR on to the backend so that we
can lower the loads to a non-volatile SEND. This allows the scheduler to
freely reorder them around stores or fences.

Our scheduler is overly conservative about reordering instructions
around memory writes or fences. Fortunately, there are several simple
assumptions we can make about our IR to schedule these things a lot
more fluidly:
* Unless its an EOT, a SEND instruction's side effects will only be
observed through other SEND instructions
* The effects of workgroup barriers, memory fences, and BRW_OPCODE_SYNC,
are only used in the IR to synchronize SEND instructions
* All other scheduler dependencies related to memory access are already
expressed through the source and destination operands

Some cooperative properties are defined by the driver itself and
are not a property of the HW. In particular whether the scope is
subgroup or workgroup is not directly related to the HW.
It could make sense encode the DPAS combinations into intel_device_info
but we are not using all possible combinations yet and wouldn't be very
useful in practice.
The new scheme was based on radv and will set us up for also filling
the flexible dimensions properties too.
Note: this also fixes a subtle issue where ARL was incorrectly inheriting
the PRE_XEHP configurations which included FLOAT16/FLOAT16/FLOAT16/FLOAT16
which it does not support.

Since we don't have any DPAS-based implementation of those, it is odd to

I've pulled in a pile of changes to reduce the overhead (runtime and
memory) when sharding for deqp-runner, along with a bunch of fixes for
KHR_display testing that we recently enabled, plus a few others that
affect our drivers.
The big new set of failures looks like it's from more complete coverage of
blitting between formats.

SEND operands don't have regions or types, hardware don't use those
bits except for possibly an old workaround. So from the perspective
of assembler, we shouldn't need to add them. For now brw_asm grammar
requires at least a type, so normalize to UD.
This will make easier to swap the parser syntax and code later.

From the perspective of assembler, regions and types for ARF null are
not relevant -- so ignore them. We still have some validation relying
on the byte-stride of the destination, so keep those for now.
In the long run, if a certain Gfx version HW requires some specific
matching, the encoder (or the parser) should take care of it.
This change will make easier to swap the parser syntax and code later.

The previous change avoids 0.25MB (1%) size change on the driver binary file,
but blocks the runtime enablement for some intel tools which is critical
to our optimization tasks.
It's not a good tradeoff based on the new need of the tool in runtime,
so revert this change.
