Label IDVS variants as being MESA_SHADER_{POSITION, VARYING} stages;
reserve the MESA_SHADER_VERTEX label for non-IDVS shaders. This reduces
confusion where a single shader compiles to two MESA_SHADER_VERTEX
shaders with different stats.
While we're at it, de-vendor the blend shader stage name; these stats
are internal anyway.

C++ requires explicit casts from integers to enums. Fixes errors like
the following when trying to use Asahi GenXML from a GTest unit test.
src/asahi/lib/agx_pack.h:554:23: error: assigning to 'enum agx_channels' from incompatible type 'uint64_t' (aka 'unsigned long long')
values->channels = __gen_unpack_uint(cl, 0, 6);

Required to clamp array indices against the array sizes per the GLSL
spec. Metal also does this, implying it's required by the hardware for
correct operation.

The texture descriptor we construct for reloading needs to respect the
surface's texture/layer selection. Fix exactly the same bug as
b8c31ac06d ("lima: fix glCopyTexSubImage2D").
Fixes:
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_rgb
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_rgba
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.cube_rgb

Streamline access to particular layer/levels. These patterns show up
across the driver and are easy to screw up, so add a helper.

As far as I can tell, these *must* be tiled. Other than that, the

We can only use linear for 2D images, not even 2D arrays. Even for 2D
images, we only want to use linear if:
* We are required to use linear due to window system requirements.
* The texture is streaming.
Otherwise, we want to use tiled textures. (Or better, compressed, but we
don't support that yet.)

nir_alu_instr_is_comparison needs to consider all comparison opcodes regardless
of size. Otherwise, they will be missed by nir_opt_move/sink.
Without this change, lowering booleans to integers regresses register
pressure (and spills/fills) significantly in certain shaders on Panfrost,
like android/com.miHoYo.GenshinImpact/1420.shader_test.

This hazard exists but is obscure enough to be missed on our existing test

This is a very obscure encoding restriction in the Bifrost ISA. Unknown if any
real apps or tests hit this, but we still need to get it right sadly.
