This adds support of the additional blending factors to the blend function
itself, and also enables testing of it in lp_test_blend (which passes).
Still need to add the glue code of linking fs shader outputs to blend inputs
in llvmpipe, and probably need to add special handling if destination doesn't
include alpha (which lp_test_blend doesn't test).

There can be other per-thread data than just vis_counter, so pass a struct
around instead (some of our non-public code uses this already and this
difference is a major cause of merge pain).

The exa core will already set the pointer to NULL prior calling
the callback function. So don't bail out in the callback if it's
already NULL.

Append the overloaded vector type used for passing in the addressing
parameters.
Without this, LLVM uses the same function signature for all those types,
which cannot work.
Fixes problems e.g. with FlightGear and Red Eclipse.
Was using the pixel size instead of the number of block for the slice
tile max computation which resulted in dma writing at wrong address.

The GLSL compiler can simplify clamp(v,0,1) to saturate. The state tracker
doesn't use it yet, but it will.

We weren't emitting the SVGA_RS_OUTPUTGAMMA state so sRGB rendering

The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt()
and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED
query says it's supported by the driver.
Otherwise, sqrt(x) is implemented with x*rsq(x). The problem with
this is sqrt(0) must be handled specially because rsq(0) might be
Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined). In the
glsl-to-tgsi code we use an extra CMP to check if x is zero and then
replace the result of x*rsq(x) with zero.
In the end, this makes sqrt() generate much more reasonable code for
drivers that can do square roots.
Note that many of piglit's generated shader tests use the GLSL
distance() function.
In particular, the LOD bias and depth comparison values are packed before the
'normal' texture coordinates, and the array slice and LOD values are appended.

This along with the latest drm-fixes branch should help with bad performance
of MSAA. Remember: Nx MSAA can't be more than N times slower (where N=2,4,6).
Anyway, I recommend at least 512 MB of VRAM for Full HD 6x MSAA.
NOTE: This is a candidate for the 9.1 branch.
