this is just the program-based handling, which means finding the right
variant and/or creating new ones based on matching a 32bit mask indicating
which textures must be rewritten

this differs in that it doesn't handle images and also doesn't filter
based on sampler type, instead using a 32bit mask for determining which
samplers to rewrite
also zink doesn't use sampler derefs

Based on hardware behaviour, it appears vertex_id is zero-based with the legacy
geometry flow but not with the new malloc IDVS flow. Since the geometry flow is
per-shader (not per-machine), there's not a good way to communicate this to NIR.
Rather than trying to shoehorn this obscure detail into NIR, just do the
lowering ourselves instead of in NIR. It's not much more code anyway.

Our swizzle lowering optimizations depend on replication of scalar fp16. This
holds on Bifrost (at least for now), but not on Valhall which has proper support
for write masks. For now, enforce Bifrost-compatible behaviour as we do not make
use of the write masks on Valhall yet.

Replace LOAD.ubo with LD_BUFFER since the .ubo segment doesn't exist on Valhall.
We could do this with a lowering pass instead but this is probably fine.

It is unclear if FP32 point sizes are supported on Valhall -- I can't get the
DDK to use them at any rate. Always lower them to FP16 and store them as FP16
for hardware use.

Varying stores was changed in Valhall. Rather than using attribute descriptors
like on Bifrost and Midgard, on Valhall we store to memory directly with
hardware-allocated buffers. This requires a new implementation of store_output,
with special provisions for writing gl_PointSize from a position shader.

Memory-allocated IDVS requires special varying load instructions that take an
offset into the hardware-allocated varying buffer, as opposed to a varying slot.
Emit these instructions.

This affects what instructions the fragment shader uses. Will be used for the
legacy geometry flow in blit shaders. Whether that is a good idea remains to be
seen, admittedly.

Valhall uses an updated version fo the TEXC path. To avoid disrupting the
existing Bifrost code, add a new Valhall-specific texture path that generates
the new-style texture instructions.

Fewer arguments compared to Bifrost; the corresponding information is encoded in

On Bifrost, this is handled in the scheduler. Until we grow a Valhall scheduler,
add a NOP with the appropriate flow control. This is correct but carries a small
performance cost.

Something an instruction has two logic flow controls, namely wait + reconverge.
These are orthogonal -- we need to insert a NOP to handle this. Add a lowering
pass that works out flow control to replace the ad hoc previous va_pack_flow.

Similar to pipeline statistics but done for a single counter.
We use REG_A6XX_RBBM_PRIMCTR_7 to get generated primitives
and not PRIMCTR_8 because PRIMCTR_7 counts pre-clipped prims
while PRIMCTR_8 counts them after clipping.
OpenGL spec for GL_PRIMITIVES_GENERATED says:
"Subsequent rendering will increment the counter once for every
vertex that is emitted from the geometry shader, or from the
vertex shader if no geometry shader is present."
