- we don't usually need to flush TC L2
- we should flush KCACHE
(not really an issue now since we always flush KCACHE when updating
descriptors, but it could be a problem if we used CE, which doesn't
require flushing KCACHE)
- add an explicit VS_PARTIAL_FLUSH flag

So that TC L2 doesn't need to be flushed.
The only problem is with index buffers, which don't use TC.
A simple solution is added that flushes TC L2 before a draw call (TC_L2_dirty).

It's causing problems, because we mix uncached CP DMA with cached WRITE_DATA
when updating the same memory.
The solution for SI is to use uncached access here, because CP DMA doesn't
support cached access.
CIK will be handled in the next patch.

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

It doesn't do anything useful. And colors are floating-point, so we can use
fs.interp, remove "flatshade" from the shader key, and rely on the FLAT_SHADE
state only (in the next patch).

Ordered compares are what you have in C. Unordered compares are the result
of negating ordered compares (they return true if either argument is NaN).
That special NaN behavior is completely useless here, and unordered
compares produce horrible code with all stable LLVM versions.
(I think that has been fixed in LLVM git)

- the relocs array is unused, remove it
- ndw is at most 115 (init), set 140 as the maximum
- compute needs 4 buffers per state, graphics only needs 1; set 4 as the maximum

From GL 4.4 Core profile:
If both PRIMITIVE_RESTART and PRIMITIVE_RESTART_FIXED_INDEX are
enabled, the index value determined by PRIMITIVE_RESTART_FIXED_INDEX is
used. If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
performed for array elements transferred by any drawing command not taking a
type parameter, including all of the *Draw* commands other than *DrawEle-
ments*.

v2: Instead of telling the driver that the window system ancillaries have
been invalidated (when the driver doesn't know which of its buffers
are the window system's!), introduce a method for invalidating
specific surfaces.

This is part of the EGL spec, and is useful for a tiled renderer to avoid
the memory bandwidth cost of storing the depth/stencil buffers.

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.
The "normal" detection (querying clflush size) already made sure it is
non-zero, however another method did not. This lead to crashes if this
value happened to be zero (apparently can happen in virtualized environments
at least).
