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.

The main idea is to avoid setting CB_COLORi_INFO = 0 for i>0 repeatedly
when those colorbuffers aren't used. This is mainly for glamor.
Same for DB. Z_INFO and STENCIL_INFO need to be cleared only once.

- convert 16 states to 1 atom
- only emit 1 scissor if VIEWPORT_INDEX isn't written
- use only one packet when emitting consecutive scissors

This is analogous to r300_mark_atom_dirty() used by r300, and will
be used by later patches. For common radeon code, appropriate helper
is called through a function pointer.
No functional changes.

Disabling the FP16 mode didn't help.
If needed, we can use this trick for blits too, but not for scaled blits.

This isn't pretty and I'd suggest it the pm4 interface builder
could be tweaked to do this more efficently, but I'd need
guidance on how that would look.
This seems to pass the few piglit tests I threw at it.
v2: handle passing layer/viewport index to fragment shader.
fix crash in blit changes,
add support to io_get_unique_index for layer/viewport index
update docs.
v3: avoid looking up viewport index and layer in es (Marek).

That's either framebuffer caches or caches for shader resources.
The motivation is that framebuffer caches need to be flushed very rarely
here.

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
for r600g and radeonsi, which was caused by an incorrect CMASK size
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.

This will be used for changing texture properties without modifying
pipe_resource like r600g, but not in this series. For now, this change
allows consolidation of pipe_surface functions.
