the coordinates were needed by seeing whether the fragment shader used

BRW_WM_NONPERSPECTIVE_CENTROID_BARYCENTRIC instead. In the future,

i965: Compute dFdy() correctly for FBOs.
On i965, dFdx() and dFdy() are computed by taking advantage of the
fact that each consecutive set of 4 pixels dispatched to the fragment
shader always constitutes a contiguous 2x2 block of pixels in a fixed
arrangement known as a "sub-span". So we calculate dFdx() by taking
the difference between the values computed for the left and right
halves of the sub-span, and we calculate dFdy() by taking the
difference between the values computed for the top and bottom halves
of the sub-span.
However, there's a subtlety when FBOs are in use: since FBOs use a
coordinate system where the origin is at the upper left, and window
system framebuffers use a coordinate system where the origin is at the
lower left, the computation of dFdy() needs to be negated for FBOs.
This patch modifies the fragment shader back-ends to negate the value
of dFdy() when an FBO is in use. It also modifies the code that
populates the program key (brw_wm_populate_key() and
brw_fs_precompile()) so that they always record in the program key
whether we are rendering to an FBO or to a window system framebuffer;
this ensures that the fragment shader will get recompiled when
switching between FBO and non-FBO use.
This will result in unnecessary recompiles of fragment shaders that
don't use dFdy(). To fix that, we will need to adapt the GLSL and
NV_fragment_program front-ends to record whether or not a given shader
uses dFdy(). I plan to implement this in a future patch series; I've
left FIXME comments in the code as a reminder.
Fixes Piglit test "fbo-deriv".

radeon/llvm: Use the VLIW Scheduler for R600->NI
It's not optimal, but it's better than the register pressure scheduler
that was previously being used. The VLIW scheduler currently ignores
all the complicated instruction groups restrictions and just tries to
fill the instruction groups with as many instructions as possible.
Though, it does know enough not to put two trans only instructions in
the same group.
We are able to ignore the instruction group restrictions in the LLVM
backend, because the finalizer in r600_asm.c will fix any illegal
instruction groups the backend generates.
Enabling the VLIW scheduler improved the run time for a sha1 compute
shader by about 50%. I'm not sure what the impact will be for graphics
shaders. I tested Lightsmark with the VLIW scheduler enabled and the
framerate was about the same, but it might help apps that use really
big shaders.

i965/msaa: Disable unsupported formats.
Due to hardware limitations, MSAA is unsupported on Gen6 for formats
containing >64 bits of data per pixel. From the Sandy Bridge PRM,
vol4 part1, p72 ("Surface Format"):
If Number of Multisamples is set to a value other than
MULTISAMPLECOUNT_1, this field cannot be set to the following
formats:
- any format with greater than 64 bits per element
- any compressed texture format (BC*)
- any YCRCB* format
Gen7 has a similar, but less stringent limitation: formats with >64
bits of data per pixel only support 4x MSAA.
This patch causes the unsupported formats to report
GL_FRAMEBUFFER_UNSUPPORTED.
Fixes piglit "multisample-formats" tests on Gen6.

llvmpipe: Simplify and fix system variables fetch.
The system array values concept doesn't really because it expects the
system values to be fixed per call, which is wrong for gl_VertexID and
iffy for gl_SampleID. So this patch does two things:
- kill the array, have emit_fetch_system_value directly pick the
values it needs (only gl_InstanceID for now, as the previous code)
- correctly handle the expected type in emit_fetch_system_value

i965: Fix brw_swap_cmod() for LE/GE comparisons.
The idea here is to rewrite comparisons like 2 >= x with x <= 2; we want
to simply exchange arguments, not negate the condition. If equality was
part of the original comparison, it should remain part of the swapped
version.
This is the true cause of bug #50298. It didn't manifest itself on
Sandybridge because we embed the conditional modifier in the IF
instruction rather than emitting a CMP. All other platforms use CMP.
It also didn't manifest itself on the master branch because commit
be5f27a84d ("glsl: Refine the loop instruction counting.") papered over
the problem.
NOTE: This is a candidate for stable release branches.
