This is not so trivial, because we disable blending if the dual src
blending is turned on and the number of color outputs is less than 2.
I decided to create 2 command buffers in the blend state object and just
switch between them when needed, because there are other states unrelated
to blending (like the color mask) and those shouldn't be changed
(the old code had it wrong).

r600g: remove the "atom" variable from r600_command_buffer
r600_command_buffer is not an atom.
The "atoms" have evolved into state slots (or groups of state slots) where
you can bind states. There is a fixed amount of atoms (state slots)
in the context.
The command buffers are nothing like that. They represent states, not state
slots.
We could probably give r600_atom a better name someday.

r600g: ensure PERFECT_ZPASS+NOOP_CULL_DISABLE are 0 for blits+decompression
When an occlusion query was active, the derived DB state wasn't changed
for u_blitter even though all the occlusion queries were suspended.
It's fixed by moving the state update into the emit functions, which are
called whenever queries are stopped or suspended.
r600g: don't modify pipe_resource in resource_copy_region, fixing race condition
pipe_resource can be shared between contexts, we shouldn't modify its
description. Instead, let's use the resource "views" (sampler views and
surfaces), where we can freely change almost any property of a resource.
When using u_blitter, the state was being saved from saved_*, but we
don't use that. So after u_blitter resumed we got some corrupted
state in.
So let's just remove the saved_* stuff. I thought it was weird but
harmless, it's actually broken.
Since we started doing fixups for different render target formats,
this has been an issue. Instead just don't do anything, when the
program gets emitted later it'll get the correct fixup.
Fixes a bunch of piglit tests.
radeonsi: Better indexing of parameters in the pixel shader.
We were previously using the TGSI input index, which can exceed the number of
parameters passed from the vertex shader via the parameter cache. Now we use
a separate index which only counts those parameters.
Prevents piglit regressions with the following fix.

r600g: Fix bug when adding new items to the compute memory pool
The items are ordered in the item list by their offsets, with the lowest
offset coming first in the list. The old code was assuming that new
items being added to the list would always have a greater offset than
the first item in the list, however this is not always the case.
This can be used to initialize the CB* registers for buffers without a
radeon_surface.
