Technically, the Vulkan spec requires that we return valid entrypoints
for all core functionality and any available device extensions. This
means that, for gen-specific functions, we need to return a trampoline
which looks at the device and calls the right device function. In 99%
of cases, the loader will do this for us but, aparently, we're supposed
to do it too. It's a tiny increase in binary size for us to carry this
around but really not bad.

The Vulkan spec annoyingly requires us to track what core version and
what all extensions are enabled and only advertise those entrypoints.
Any call to vkGet*ProcAddr for an entrypoint for an extension the client
has not explicitly enabled is supposed to return NULL.

The kernel is moving to a $class$instance naming scheme in preparation
for accommodating more rings in the future in a consistent manner. It is
already using the naming scheme internally, and now we are looking at
updating some soft-ABI such as the error state to use the new naming
scheme. This of course means we need to teach aubinator_error_decode how
to map both sets of ring names onto its register maps.

From the Vulkan spec with KHX extensions:
"If queries are used while executing a render pass instance that has
multiview enabled, the query uses N consecutive query indices
in the query pool (starting at query) where N is the number of bits
set in the view mask in the subpass the query is used in.
How the numerical results of the query are distributed among the
queries is implementation-dependent. For example, some implementations
may write each view's results to a distinct query, while other
implementations may write the total result to the first query and write
zero to the other queries. However, the sum of the results in all the
queries must accurately reflect the total result of the query summed
over all views. Applications can sum the results from all the queries to
compute the total result."
In our case we only really emit a single query (in the first query index)
that stores the aggregated result for all views, but we still need to manage
availability for all the other query indices involved, even if we don't
actually use them.
This is relevant when clients call vkGetQueryPoolResults and pass all N
queries to retrieve the results. In that scenario, without this patch,
we will never see queries other than the first being available since we
never emit them.
v2: we need the same treatment for timestamp queries.
v3 (Jason):
- Better an if instead of an early return.
- We can't write to this memory in the CPU, we should use
MI_STORE_DATA_IMM and emit_query_availability (Jason).
v4 (Jason):
- No need to take the value to write as parameter, just hard code it to 0.

Previously the dataflow propagation algorithm would calculate the ACP
live-in and -out sets in a two-pass fixed-point algorithm. The first
pass would update the live-out sets of all basic blocks of the program
based on their live-in sets, while the second pass would update the
live-in sets based on the live-out sets. This is incredibly
inefficient in the typical case where the CFG of the program is
approximately acyclic, because it can take up to 2*n passes for an ACP
entry introduced at the top of the program to reach the bottom (where
n is the number of basic blocks in the program), until which point the
algorithm won't be able to reach a fixed point.
The same effect can be achieved in a single pass by computing the
live-in and -out sets in lock-step, because that makes sure that
processing of any basic block will pick up the updated live-out sets
of the lexically preceding blocks. This gives the dataflow
propagation algorithm effectively O(n) run-time instead of O(n^2) in
the acyclic case.
The time spent in dataflow propagation is reduced by 30x in the
GLES31.functional.ssbo.layout.random.all_shared_buffer.5 dEQP
test-case on my CHV system (the improvement is likely to be of the
same order of magnitude on other platforms). This more than reverses
an apparent run-time regression in this test-case from my previous
copy-propagation undefined-value handling patch, which was ultimately
caused by the additional work introduced in that commit to account for
undefined values being multiplied by a huge quadratic factor.
According to Chad this test was failing on CHV due to a 30s time-out
imposed by the Android CTS (this was the case regardless of my
undefined-value handling patch, even though my patch substantially
exacerbated the issue). On my CHV system this patch reduces the
overall run-time of the test by approximately 12x, getting us to
around 13s, well below the time-out.
v2: Initialize live-out set to the universal set to avoid rather
pessimistic dataflow estimation in shaders with cycles (Addresses
performance regression reported by Eero in GpuTest Piano).
Performance numbers given above still apply. No shader-db changes
with respect to master.

This creates two new internal dependencies, idep_nir_headers and
idep_nir. The former encapsulates the generation of nir_opcodes.h and
nir_builder_opcodes.h and adding src/compiler/nir as an include path.
This ensures that any target that needs nir headers will have the
includes and that the generated headers will be generated before the
target is build. The second, idep_nir, includes the first and
additionally links to libnir.
This is intended to make it easier to avoid race conditions in the build
when using nir, since the number of consumers for libnir and it's
headers are quite high.

Gen 10 has a strange hardware bug involving V immediates with W types.
It appears that a mov(8) g2<1>W 0x76543210V will actually result in g2
getting the value {3, 2, 1, 0, 3, 2, 1, 0}. In particular, the bottom
four nibbles are repeated instead of the top four being taken. (A mov
of 0x00003210V yields the same result.) This bug does not appear in any
hardware documentation as far as we can tell and the simulator does not
implement the bug either.
Commit 6132992cdb was mostly a no-op
except that it changed the type of the subgroup invocation from UW to W
and caused us to tickle this bug with basically every compute shader
that uses any sort of invocation ID (which is most of them). This is
also potentially an issue for geometry shader input pulls and SampleID
setup. The easy solution is just to change the few places where we use
a vector integer immediate with a W type to use a UW type.

If we have a color attachment, but its writes are masked, this would
have still returned true. This is inconsistent with how HasWriteableRT
in 3DSTATE_PS_BLEND is set, which does take the mask into account.
This could lead to PixelShaderHasUAV not being set in 3DSTATE_PS_EXTRA
if the fragment shader does use UAVs, meaning the fragment shader may
not be invoked because HasWriteableRT is false. Specifically, this was
seen to occur when the shader also enables early fragment tests: the
fragment shader was not invoked despite passing depth/stencil.
Fix by taking the color write mask into account in this function. This
is consistent with how things are done on i965.
