intel/compiler: Move Gen4/5 rounding to visitor

Gen4/5's rounding instructions operate differently than later Gens'.
They all return the floor of the input and the "Round-increment"
conditional modifier answers whether the result should be incremented by
1.0 to get the appropriate result for the operation (and thus its
behavior is determined by the round opcode; e.g., RNDZ vs RNDE).

Since this requires a second instruciton (a predicated ADD) that
consumes the result of the round instruction, the round instruction
cannot write its result directly to the (write-only) message registers.
By emitting the ADD in the generator, the backend thinks it's safe to
store the round's result directly to the message register file.

To avoid this, we move the emission of the ADD instruction to the NIR
translator so that the backend has the information it needs.

I suspect this also fixes code generated for RNDZ.SAT but since
Gen4/5 don't support GLSL 1.30 which adds the trunc() function, I
couldn't write a piglit test to confirm. My thinking is that if x=-0.5:

      sat(trunc(-0.5)) = 0.0

But on Gen4/5 where sat(trunc(x)) is implemented as

      rndz.r.f0  result, x             // result = floor(x)
                                       // set f0 if increment needed
      (+f0) add  result, result, 1.0   // fixup so result = trunc(x)

then putting saturate on both instructions will give the wrong result.

      floor(-0.5) = -1.0
      sat(floor(-0.5)) = 0.0
      // +1 increment would be needed since floor(-0.5) != trunc(-0.5)
      sat(sat(floor(-0.5)) + 1.0) = 1.0

panfrost: Rework linear<--->tiled conversions

There's a lot going on here (it's a ton of commits squashed together
since otherwise this would be impossible to review...)

1. We have a fast path for linear->tiled for whole (aligned) tiles, but we
have to use a slow path for unaligned accesses. We can get a pretty
major win for partial updates by using this slow path simply on the
borders of the update region, and then hit the fast path for the
tile-aligned interior. This does require some shuffling.

2. Mark the LUTs constant, which allows the compiler to inline them,
which pairs well with loop unrolling (eliminating the memory accesses
and just becoming some immediates.. which are not as immediate on
aarch64 as I'd like..)

3. Add fast path for bpp1/2/8/16. These use the same algorithm and we
have native types for them, so may as well get the fast path.

4. Drop generic path for bpp != 1/2/8/16, since these formats are
generally awful and there's no way to tile them efficienctly and
honestly there's not a good reason too either. Lima doesn't support any
of these formats; Panfrost can make the opinionated choice to make them
linear.

5. Specialize the unaligned routines. They don't have to be fully
generic, they just can't assume alignment. So now they should be nearly
as fast as the aligned versions (which get some extra tricks to be even
faster but the difference might be neglible on some workloads).

6. Specialize also for the size of the tile, to allow 4x4 tiling as well
as 16x16 tiling. This allows compressed textures to be efficiently tiled
with the same routines (so we add support for tiling ASTC/ETC textures
while we're at it)

panfrost,lima: De-Galliumize tiling routines

There's an implicit dependence on Gallium here that will add more
complexity than needed when testing/optimizing out of driver as well as
potentially Vulkanizing. We don't need a full pipe_box, just the x/y/w/h
properties directly.

do its thing even on debug builds.

I strongly suspect it was supposed to be a typedef. However, used
nowhere, we should remove it.
