Mostly for consistency with the other decompress functions, but note that
in the non-DCC decompress case, the function can now early-out in slightly
more (albeit probably rare) cases.

This happens to "fix" a rendering bug in KotOR2, because it avoids a still
not quite understood bug with MSAA fast stencil clear decompress. For the
stencil clear bug, I have sent a piglit test (arb_texture_multisample-stencil-clear).

This is in preparation of raising the number of exposed sampler views to 32
bits, which will raise the total number of sampler views to 33 for the
polygon stipple texture. That texture should never be compressed (and it's
certainly not a depth texture), but this approach seems cleaner to me than
special-casing the last slot in all affected code paths.

Since it is all about calling into blitter functions, it makes more

The texture slot is expanded to 16 dwords containing 2 descriptors.
Those can be:
- Image and fmask, or
- Image and sampler state
By carefully choosing the locations, we can put all three into one slot,
with the fmask and sampler state being mutually exclusive.
This improves shaders in 2 ways:
- 2 user SGPRs are unused, shaders can use them as temporary registers now
- each pair of descriptors is always on the same cache line
v2: cosmetic changes: add back v8i32, don't load a sampler state & fmask
at the same time

Uses the DCC buffer instead of the CMASK buffer. The ELIMINATE_FAST_CLEAR
still works. Furthermore, with DCC compression we can directly clear
to a limited set of colors such that we do not need a postprocessing step.

The "current" shader pointer is moved from the CSO to the context, so that
the CSO is mostly immutable.
The only drawback is that the "current" pointer isn't saved when unbinding
a shader and it must be looked up when the shader is bound again.
This is also a prerequisite for multithreaded shader compilation.

Same for DB. Z_INFO and STENCIL_INFO need to be cleared only once.

That's either framebuffer caches or caches for shader resources.

This fixes 3D texture support in all these cases, because array_size is 1
with 3D textures and depth0 actually contains the "array size".
util_max_layer is universal and returns the last layer index for any texture
target.
A lot of the cases below can't actually be hit with 3D textures, but let's
be consistent.
This fixes a failure in:
piglit layered-rendering/clear-color-all-types 3d single_level

calculation.

Sampler descriptors are now represented by si_descriptors.
This also adds support for fine-grained sampler state updates and
the border color update is now isolated in a separate function.
Border colors have been broken if texturing from multiple shader stages is
used. This patch doesn't change that.
BTW, blitting already makes use of fine-grained state updates.
u_blitter uses 2 textures at most, so we only have to save 2.
