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
a Valhall-specific blend shader prologue instead.

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.

We need a slightly different idiom on Valhall, since the segment modifiers no
longer exist but we now have an immediate offset.

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.
Fixes dEQP-GLES31.functional.ssbo.layout.single_basic_type.shared.lowp_vec3.

These use the attribute pipe, the new versions of LD_ATTR_TEX, but reading
texture descriptors instead of attribute descriptors unlike their Bifrost
predecessors.

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."
Passes tests:

The loader extension provides upcalls to get surface state (native
resource and size) into the driver. The driver extension is called by a
kopper-aware loader in preference to __DRI_SWRAST's createNewDrawable.
