Mesa now has a statistics framework. This adds support for emitting
additional statistics about PowerVR shaders for the Rogue architecture.
Add support for emitting the following statistics: Code size, scratch
size, spill count, temp count, loop count, number of inst groups, number
of main inst groups, number of bitwise inst groups and number of control
inst groups.
Add support for new PCO_DEBUG_PRINT option "stats" to emit shader stats.

Add a new PIPE_CAP_CLEAR_MASKED capability that allows drivers to
handle buffer clears with color and stencil masks directly, instead
of falling back to drawing a quad in Mesa.
This patch introduces several changes:
1. Add the new pipe cap PIPE_CAP_CLEAR_MASKED to pipe_defines.h and
document it in the Gallium screen documentation.
2. Add color_clear_mask and stencil_clear_mask parameters to the
pipe_context::clear() hook:
- color_clear_mask (uint32_t): contains 4 color mask bits per draw buffer
(max 8 buffers = 32 bits)
- stencil_clear_mask (uint8_t): contains the stencil write mask (8 bits)
3. Update the state tracker to use the masked clear path when the
driver supports it:
- Pass ctx->Color.ColorMask for color buffer clears
- Pass ctx->Stencil.WriteMask for stencil clears
- Allow both color and stencil clears to avoid the quad path when
masks are present and the driver advertises support
4. Update all existing driver clear() hooks to accept the new
color_clear_mask and stencil_clear_mask parameter.
This optimization allows drivers that can efficiently handle masked
clears in hardware to do so, improving performance for applications
that frequently clear buffers with masks enabled.

Similar to the low latency option for encode, this reduces latency
of decoding at the cost of increased power usage.
Can be enabled with AMD_DEBUG=lowlatencydec

Add support for VK_EXT_blend_operation_advanced to the Honeykrisp
Vulkan driver. Extend agx_blend_rt_key with a tagged mode field
interpreted via pack/unpack helpers for standard and advanced blend
state.
The driver advertises full extension support including all operations,
independent blend, non-premultiplied colors, and correlated overlap.

ACO got a lot better at forming VOPD instructions, and testing
feedback seems to point in a slightly positive direction for this.
gfx12 will also start requiring wave32 for dynamic VGPR allocation at
some point.

Implement a mitigation for VM faults caused by SMEM reading
from NULL descriptors.
In order to satisfy VKD3D-Proton's expectations on mutable
descriptors, we must do this in shader code, it is not
sufficient to use the address of a mapped BO when writing
null descriptors. It is not feasible to mitigate this
in VKD3D-Proton.
