Only emit anything if this is a control barrier, i.e. contains an
execution scope. Also change the assertion to look at that scope
instead of the memory scope.

When the option is enabled, lower memory barriers to the
unified nir_intrinsic_scoped_barrier.
The translation of the following is based on
https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_gl_spirv.txt
- memoryBarrier()
- memoryBarrierBuffer()
- memoryBarrierImage()
- memoryBarrierShared()
- groupMemoryBarrier()
Also use scoped barrier for the memory counterparts of the GLSL
(control) barrier() when the option is enabled. The execution
part of a (control) barrier() remains using the old intrinsic.
For memoryBarrierAtomicCounter() there's no corresponding
nir_var_atomic_counter mode. Since atomic counters are lowered
to SSBOs, use the nir_var_mem_ssbo mode in the scoped barrier
instead.

autotune already divides draw-cost by # of draws, but only increments
the draw-cost once per multi-draw. We could either _also_ account for
draw-cost by multiply by # of draws for treat multi-draw as a single
draw. The latter saves an integer multiply per draw.
Fixes a performance regression triggered by transition from GMEM to
sysmem rendering.

It's started rendering something different again, with a similar sort of
bad rendering to what's linked in the bug report (though this time it's a
'P' that became a white square). Commit range 65b62db0..964323fe has
nothing particularly likely in it, so I expect this is some sort of cache
flushing fail or something.

No longer need to redirect, since the renderer should use the fixed
decoder for VkDrmFormatModifierPropertiesListEXT::drmFormatModifierCount
by now.

If a dual source blend colour is never written, src1 will be null and it will be
invalid to dereference it. src1 is dereferenced both for the f2fN instruction
but also if a dual blend factor is used... even if the latter isn't strictly
valid, segfaulting in the NIR pass seems a lot meaner than blending with zero.
The referenced commit hosed Asahi, causing anything that used blending to crash.
Panfrost is unaffected since it always supplies a dual colour due to our crude
construction of blend shaders.

RGP traces need a dump of shader code in order to display ISA and
instruction trace. Previously, this was read back from GPU at trace
creation time. However, for future changes that implements upload shader
to invisible VRAM, the upload destination will be a temporary staging
buffer and will be only accessible during shader creation.
To allow dumping in such cases, copy the shader code to a separate buffer
at creation time, if thread tracing is enabled.

some drivers may provide this in heaps that get used by non-staging resources,
so avoid extra copies in that case
unlike the previous attempt at this optimization, this utilizes the screen-based
context for thread-safe transfers, which should avoid races/crashes

G13 does not support sampler descriptor LOD biasing, so this needs to be lowered
to shader code for APIs that require this functionality. Add an option to do
this lowering while doing our other backend texture lowerings. This generates
lod_bias_agx texture instructions which the driver is expected to lower
according to its binding model.

Track the LOD bias of samplers and upload them at draw time to uniform

Vulkan will probably want to pull from a descriptor set instead.

Add a new texture opcode that returns the LOD bias of the sampler. This will be
used on AGX to lower sampler LOD bias to txb and friends. This needs to be a
texture op (and not a new intrinsic) to handle both bindless and bindful
samplers across GL and Vulkan in a uniform way.
