At least temporarily, I need to fallback to old compiler still for
relative dest (for freedreno), but I can do relative src temp. Only
a temporary situation, but seems easy/reasonable for tgsi-scan to
track this.

We were invalidating si_screen:tm by calling
r600_destroy_common_screen() which frees the si_screen object. This
caused the driver to crash in LLVMDisposeTargetMachine() since we
were passing it an invalid pointer.

It doesn't work on Windows because of STDCALL calling convention -- it's
the callee responsibility to pop the arguments, and the number of
arguments vary with the prototype --, so the stack pointer ends up getting
corrupted.
This is just a non-invasive stop-gap fix. A proper fix would be more
elaborate, and require either:
- a variation of __glapi_noop_table which sets GL_INVALID_OPERATION
error
- stop using APIENTRY on all internal _mesa_* functions.
Tested with piglit gl-1.0-beginend-coverage (it now fails instead of
crashing).

This fixes a case where a transform feedback buffer is fed back as an index
buffer, because SURFACE_SYNC must be after VS_PARTIAL_FLUSH.

- 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)

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

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.
