All the other expression types allowed here have inst->mlen == 0, and this
one has implied MRF writes for all of its payload, so nothing else in the
implementation should need to change.

We weren't setting needs_dep[i] in the loops, so we'd continue on to
potentially add the same workaround MOVs to the later basic block
boundaries, too. We can either set needs_dep[i] to exit through the
normal path, or we can just return since we know we're done.

Like we have done for the VS and for constant-index uniform loads, we use
the sampler engine to get caching in front of the L3 to avoid tickling the
IVB L3 bug. This is also a bit of a functional change, as we're now
loading a vec4 instead of a single dword, though we're not taking
advantage of the other 3 components of the vec4 (yet).
With the driver hacked to always take the varying-index path for all
uniforms, improves performance of my old GLSL demo by 315% +/- 2% (n=4).
This a major fix for some blur shaders in compositors from the
varying-index uniforms support I introduced in 9.1.

We want to load vec4s, since loading a vec4 instead of a dword is
basically no increased latency. But for variable indexed access, the
previous requirement of aligned vec4s for a sampler LD was hard to
implement.
Note that this change only affects those messages that use the surface
format, like sampler LDs, but not to the untyped data cache loads we've
used in other cases.
No significant performance difference on my GLSL demo with uniforms forced
to take the varying pull constants path (n=4).

This happens quite a bit with varying-index uniform loads. We could also

If the active uniform is an array, then the length of the uniform name should
include the three extra characters for the "[0]" suffix, which is required by
the GL 4.2 spec to be appended to the uniform name in glGetActiveUniform().
This avoids the situation where the output buffer does not have enough space
to hold the "[0]" suffix, resulting in an incomplete array specification like
"foobar[0".

We dump shader source in ir_to_mesa.cpp, and we dump linked programs here,

optimize out VS outputs, and don't interpolate FS inputs!)

If we're drawing to a surface that's 2048 x 2048 pixels or larger there's
danger of fixed-point overflow in the triangle rasterization code. That
leads to various rendering glitches.
Rather than implement some intricate changes to the rasterization code,
simply subdivide triangles into smaller subtriangles to avoid the issue.
Only do this when the drawing surface is larger than 2048 by 2048.
