Rather than building a new one every compile. This should reduce some
of the overhead of compiling shaders.
One consequence of this change is that we lose the MachineInstrs dumps
when dumping the shaders via R600_DEBUG. The LLVM IR and assembly is
still dumped, and if you still want to see the MachineInstr dump, you
can run the dumped LLVM IR through llc.
I will need this for fixing sample shading with 1 sample.
The good news is that all shader pm4 states no longer use the current context
state, so we can generate the pm4 states outside of draw_vbo if needed.

This removes the intermediate storage (pm4 state) and generates descriptors
directly in a staging buffer.
It also reduces the number of flushes, because the descriptors no longer
take CS space.

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.

I'm somewhat impressed that current gccs will let you do this, but
sufficiently old ones (including 4.4.7 in RHEL6) won't.

This code is a slightly modified version of evergreen_dma_blit (and
evergreen_dma_copy as well as evergreen_dma_copy_tile).
It would be nice to share some of the code in the long term.
I have reused some "cik"-prefixed functions that also return the right
value for SI. I am not sure if they should be renamed.

Buffers are disabled by VGT_STRMOUT_BUFFER_CONFIG, but the query only works
if VGT_STRMOUT_CONFIG.STREAMOUT_0_EN is enabled.
This moves VGT_STRMOUT_CONFIG to its own state. The register is set to 1
if either streamout or the primitives-generated query is enabled.
However, the primitives-emitted query is also incremented, so it's disabled
by setting VGT_STRMOUT_BUFFER_SIZE to 0 when there is no buffer bound.
This fixes piglit:
ARB_transform_feedback2/counting with pause
EXT_transform_feedback/primgen-query transform-feedback-disabled

This looks like r600g. The shared Cayman MSAA code is used here.
The real motivation for this is that I need the ability to change values
of color registers after the framebuffer state is set. The PM4 state cannot
be modified easily after it's generated. With this, I can just change
r600_surface::cb_color_xxx and set framebuffer.atom.dirty=true and it's done.
