Useful both for ruling out issues with shader preambles as well as (in some
cases) making for a nicer reading experience of the compiled assembly.

Kinda silly but fixes

queries the number of samples of a NONE format, required for
ARB_framebuffer_no_attachments to make sense.

Sample index and layer index are both 16-bits, even though they are zero
extended for compiler simplicity in some cases. In particular this means that 2D
MSAA arrays consume 6 half-regs for their coordinates, not 8. This is what the
IR translation (actually agx_nir_lower_texture) produces, we just need to fix
the calculation in agx_read_registers to agree.
Fixes validation failure in tests like
dEQP-GLES31.functional.texture.multisample.samples_4.use_texture_color_2d_array

This gives our shifts SM5 behaviour at the cost of a little extra ALU. That way,
we match NIR's shifts.
This fixes unsoundness of GLSL expressions like "a << (b & 31)", where the &
would mistakenly get optimized away.

vulkancts test dEQP-VK.wsi.direct_drm.surface.create_simulate_oom is failing
because in wsi_display_alloc_connector() function memory allocation for
connector is not checked for return NULL. create_simulate_oom test simulates
out of memory, hence memory allocation fails for connector and later when
tried to dereference connector program will segfault.
This patch fixes the dEQP-VK.wsi.direct_drm.surface.create_simulate_oom test
segfault issue by checking if connector is NULL afer memory allocation.

This NIR pass lowers stores in fragment shaders to:
if (!gl_HelperInvocaton) {
store();
}
This implements the API requirement that helper invocations do not have visible
side effects, and the lowering is required on any hardware that cannot directly
mask helper invocation's side effects. The pass was originally written for
Midgard (which has this issue) but is also needed for Asahi. Let's share the
code, and fix it while we're at it.
Changes from the Midgard pass:
1. Add an option to only lower atomics.
AGX hardware can mask helper invocations for "plain" stores but not for
atomics. Accordingly, the AGX compiler wants this lowering for atomics but
not store_global. By contrast, Midgard cannot mask any stores and needs the
lowering for all store intrinsics. Add an option to the common pass to
accommodate both cases.
This is an optimization for AGX. It is not required for correctness, this
lowering is always legal.
2. Fix dominance issues.
It's invalid to have NIR like
if ... {
ssa_1 = ...
}
foo ssa_1
Instead we need to rewrite as
if ... {
ssa_1 = ...
} else {
ssa_2 = undef
}
ssa_3 = phi ssa_1, ssa_2
foo ssa_3
By default, neither nir_validate nor the backends check this, so this doesn't
currently fix a (known) real bug. But it's still invalid and fails validation
with NIR_DEBUG=validate_ssa_dominance.
Fix this in lower_helper_writes for intrinsics that return data (atomics).
3. Assert that the pass is run only for fragment shaders. This encourages
backends to be judicious about which passes they call instead of just
throwing everything in a giant lower everything spaghetti.

venus utilizes the host side shader cache.
This is a WA to generate shader cache files containing headers with
a unique cache id that will change based on host driver identifiers.
This allows fossilize replay to detect if the host side shader cache
is no longer up to date.
The shader cache is destroyed after creating the necessary files and
not utilized by venus.

Strictly, this extension was already advertised, but it didn't seem nice to mark
it DONE when there was no sync support in the driver whatsoever. Mark it done
now that we do have proper explicit sync (well, in conjunction with the "add
Linux UAPI" patches that are blocked on getting the kernel driver upstream, but
that's needed for *any* of these extensions to be there!)

We need to align the extent to 4 for the GPU, but we can't copy more
than the original size out of the user buffer. Always alloc the exact
size we need.
This does mean the GPU gets an IB extent that could include some other
stuff later in the pool, if not aligned. This is probably safe? Given
the base alignment, it should never cross a page boundary and fault or
anything like that.
