This is a simple shader compiler that performs almost zero optimizations. The
generated code is usually much larger comparing to that generated by i965.
The generated code also requires many more registers.
Function-wise, it lacks register spilling and does not support most TGSI
indirections. Other than those, it works alright.
This move the tracing timeout and printing into winsys and add
an debug environement variable for it (R600_DEBUG=trace_cs).
Lot of file touched because of winsys API changes.

There was a lot of code in evergreen_compute_internal.c that was not
being used at all and most of it was duplicating code from other parts
of the driver.

New textures or vertex buffers don't always require patching and
re-emitting the shaders. So do a better job of figuring out when we
actually have to patch the shader.

clang is supports most gcc options / extensions, with a some exceptions.
The biggest advantage of using clang is that compilation times are much
short.
One can tell scons to use clang when building by invoking it as
CC=clang CXX=clang++ scons libgl-xlib
We were assigning incorrect const register for immediates, and
potentially writing immediate const to the wrong location. This fixes
an incorrect-rendering bug with xonotic.

Set a few extra registers to make sure we are in proper state for
clearing. And also add some debug options to mark all state dirty in
clear and gmem operations to aid in debugging.

There is a bit we need to set for 2D vs 3D fetch, to tell the hw whether
there are two or there valid input components.

The previous approach of using the dst register as an intermediate
temporary doesn't work in a lot of cases. For example, if the dst
register is the same as one of the src registers.
For now, just simplify it and always allocate a new register to use as
an intermediate. In some cases this will result in more registers used
than required. I think the best solution would be to implement an
optimization pass to reduce the number of registers used, which would
also solve the problem we have now of not being able to use GPRs that
are assigned for TGSI_FILE_INPUT.

Opps, didn't notice that I had left it stubbed out.
Also, make things fail a bit more gracefully when things go wrong.

Really this should be set based on buffer format, not on color vs
depth/stencil. Probably there should be more formats that set the bit
as we add support for more render target formats.

This fixes a crash when a resource cannot be mapped to the CPU's address space
because it's too big.
This puts a global pipe_context in r600_screen, which is guarded by a mutex,
so that we can use pipe_context when there isn't one around.
Hopefully our multi-context support is solid.
