0be0ad5d58 llvmpipe: intrinsics version of triangle coeficient calculation 
Looks nice, but makes almost no impact on performance - maybe
a percent or so in isosurf, nothing elsewhere.  May be of use
later on.

2184f3ec30 Revert "r600g: simplify states" 
This reverts commit bd25e23bf3.

Apart from introducing a lot of hex magic numbers and being highly impenetable code,
it causes lots of lockups on an average piglit run that always runs without lockups.

Always run piglit before/after doing big things like this.

a03d456f5a r600g: add initial if/else/endif support 
this adds handling for some more CF instructions and conditions
also adds parameter for stack size emission

These seem to pass on VS with the stack size hack but not on FS,

d8fb13bae3 r600g: optimise op2 and swapped op2 emission. 
this makes op2 emission smaller, since it skips instructions
that don't write to the dst. not sure if this could have unwanted
side effects but try it and see.

9763d0a82a i965: Start building direct GLSL2 IR to 965 assembly codegen. 
Our channel-expressions and vector-splitting changes now happen into a
private copy of the IR that we maintain for ourselves.  Uniform
assignment still happens by the core, so we continue using Mesa IR
generation not just for swrast fallbacks but also for uniform values
(since there's no storage for their contents other than
shader_program->FragmentProgram->Parameters->ParameterValues).  And
most importantly, at the moment no actual codegen is hooked up other
than emitting our favorite color to the framebuffer.

c1dfdcb93a i965: Add new pass to split vectors into scalar variables 
Combined with the previous pass, this lets other optimization passes
do their work thanks to ir_tree_grafting.  Still have regression in
instruction count with INTEL_NEW_FS, but register count is even
better.

3a8ad33dde i965: Add a pass for the FS to reduce vector expressions down to scalar. 
This is a step towards implementing a GLSL IR backend for the 965
fragment shader.  Because it has downsides with the current codegen,
it is hidden under the environment variable INTEL_NEW_FS.

This results in an increase in instruction count at the moment (1444
-> 1752 for glsl-fs-raytrace, 345 -> 359 on my demo), because dot
products are turned into a series of multiplies and adds instead of a
custom expansion of MULs and MACs, and by not splitting the variable
types up we don't get tree grafting and thus there are extra moves of
temporary storage.  However, register count drops for the non-GLSL
path (64 -> 56 on my demo shader) because the register allocator sees
all the sub-operations.
