As pointed out by Boris, what we were calling PAN_LINEAR depth textures
was in fact u-interleaved tiled (!), but we never noticed since we
flipped the flag used for sampling, leading to all sorts of fun bugs
when attempting to directly acess depth textures from the CPU. Which
begs the question -- if what we called LINEAR was tiled, how do we
actually render linear depth textures? It turns out the flags for AFBC
form a mali_block_format 2-bit code just like their render-target
counterparts, so we can render to any of the above.

It has been unused for a while; let's just remove the abstraction.
Technically the hardware does support 32-bit job descriptors, but we

There's only one way to encode comparison functions in the command
stream, not two. It's just that the semantics for texture comparisons
are flipped from the semantics of stencil comparison. We can factor out
that flip to common Panfrost code, rather than tying it to a second
Gallium routine.

Just like varyings have special records for point coordinates (etc),
attributes have special records for vertex/instance ID. We can parse
these fairly easily, although they don't line up exactly with normal
attribute records.

The algorithm is as described. Nothing fancy here, just need to add some
new code paths depending on which model we're running on.
Tomeu:
- Also disable tiling when !hierarchy and !vertex_count
- Avoid creating polygon lists smaller than the minimum when
vertex_count > 0 but tile size smaller than 16 byte
- Take into account tile size when calculating polygon list size for
!hierarchy
- Allow 0-sized tiles in a single dimension

The hardware doesn't care, and a lot of Panfrost code relies on an
