OpenCL may load and store vec16 data, while ACO only
support <=32byte. Radeonsi is going to use
ac_nir_lower_mem_access_bit_sizes() for lowering these
access.

This adds kill_z and kill_stencil flags to the shader PS epilog key, which
removes those outputs if depth or stencil are disabled.
It must be implemented in:
* ACO PS epilog
* LLVM PS epilog
* ac_nir_lower_ps for monolithic shaders
Some of the samplemask code wasn't completely correct, but probably harmless.

Cross-invocation TCS input access doesn't prevent same-invocation access.
This improves shaders that use both for the same inputs.
Also, if some components of a vec4 slot only use same-invocation access and
other components only use cross-invocation access (it's possible after
compaction), this takes the VGPR path for the components with
same-invocation access, which didn't happen previously because all masks
only describe whole vec4s.

Both can be used. Cross-invocation access can read it from LDS, while
same-invocation access can read it from VGPRs.
The entrypoints of the passes don't allow that flexibility yet,
but the logic inside the pass allows it.

ACO is still not perfect:
* It generates s_wait_loadcnt 0x0-0x3 when the only required wait instruction
is s_wait_loadcnt 0x5.
* It generates a lot of unnecessary jumps and blocks for uniform loop breaks.
Only scc1 jumps are necessary to break the loop. This is 10x better than
LLVM, but even ACO might consider using nir_intrinsic_ordered_add_loop_gfx12_amd
for the best performance.

This configuration will be enabled in RADV in a subsequent commit.
On GFX10.3:
Do this together with the primitive export, to avoid adding extra
CF, and to ensure optimal access of the export space.
On GFX11:
It's not an export but a memory store instruction, so always do
it earlier and ensure the optimal attribute ring access pattern.

When alpha-to-coverage and alpha-to-one are both enabled in the
fragment shader, the alpha value should be exported through MRTZ and
one to MRT0.a. Otherwise, alpha-to-one will be performed before
alpha-to-coverage.

They are a maintainenance burden since they would need changes to
support more instruction types that nir_opt_varyings will be able to
move between shaders, and they are almost identical to
default_varying_estimate_instr_cost, so just use that.
The cost threshold is adjusted for AMD because
default_varying_estimate_instr_cost is slightly different.

This patch:
- adds a new subquery (AMDGPU_INFO_UQ_FW_AREAS) in AMDGPU_INFO_IOCTL
to get the size and alignment of shadow and csa objects from the
kernel. This information is required for a userqueue consumer (like
MESA/libdrm) to create the userqueue metadata objects properly.
- also adds supporting metadata structures and a high level wrapper
function (amdgpu_query_uq_metadata_info) to the query, to make it
easy to use.
The corresponding kernel changes for this UAPI extension can be found
in amd-gfx mailing list, link:
https://patchwork.freedesktop.org/patch/621390/?series=139715&rev=2
This patch adds support only for the GFX IP, and the other engines may
be supported in subsequent development.
