i965: Only use brw_draw.c's trim() function when necessary.
brw_draw.c contains a trim() function which modifies the vertex count
for quads and quad strips in order to discard dangling vertices. In
principle this shouldn't be necessary, since hardware since Gen4 is
capable of discarding dangling vertices by itself. However, it's
necessary because as a hack to speed up rendering on Gen 4-5, we
sometimes convert quads to trifans and quad strips to tristrips. The
trim() function isn't necessary on Gen6 and up.
This patch documents why and when the trim() function is necessary,
and avoids calling it when it's not needed.

primitive restart of quads and quad strips on Haswell.

glsl/linker: Reduce scope of non-flat integer varying fix.
In the mailing list discussion of "glsl/linker: fix varying packing

7862bde), we concluded that
since the bug only applies to integral variables, it is safer to just
apply the bug fix to integer varyings. I forgot to make the change

glsl/linker: Adapt flat varying handling in preparation for geometry shaders.
When a varying is consumed by transform feedback, but is not used by
the fragment shader, assign_varying_locations() sets its interpolation
type to "flat" in order to ensure that lower_packed_varyings never has
to deal with non-flat integral varyings (the GLSL spec doesn't require
integral vertex outputs to be flat if they aren't consumed by the
fragment shader).
A similar situation will arise when geometry shader support is added,
since the GLSL spec only requires integral vertex shader outputs to be
flat when they are consumed by the fragment shader. This patch
modifies the linker to handle this situation too.

glsl/linker: fix varying packing for non-flat integer varyings.
Commit
dfb57e7 (glsl: Fix error checking on "flat" keyword to match
GLSL ES 3.00, GLSL 1.50) relaxed the rules for integral varyings: they
only need to be declared as "flat" if they are a fragment shader
inputs. This allowed for the possibility of a vertex shader output
being a non-flat integer, provided that it was not matched to a
fragment shader input. A non-contrived situation where this might
arise is if a vertex shader generates some integral outputs which are
consumed by tranform feedback, but not by the fragment shader.
Unfortunately, lower_packed_varyings assumes that *all* integral
varyings are flat, regardless of whether they are consumed by the
fragment shader. As a result, attempting to create a non-flat
integral vertex output of a size that required packing (i.e. a size
other than ivec4 or uvec4) would cause an assertion failure in
lower_packed_varyings.
This patch prevents the assertion failure by forcing vertex shader
outputs to be "flat" whenever they are not consumed by the fragment
shader. This should have no effect on rendering since the "flat"
keyword only affects the behaviour of fragment shader inputs.
Fixes piglit test "spec/EXT_transform_feedback/nonflat-integral".

i965: Remove fixed-function texture projection avoidance optimization.
This optimization attempts to avoid extra attribute interpolation
instructions for texture coordinates where the W-component is 1.0.
Unfortunately, it requires a lot of complexity: the brw_wm_input_sizes
state atom (all the brw_vs_constval.c code) needs to run on each draw.
It computes the input_size_masks array, then uses that to compute
proj_attrib_mask. Differences in proj_attrib_mask can cause
state-dependent fragment shader recompiles. We also often fail to guess
proj_attrib_mask for the fragment shader precompile, causing us to
needlessly compile it twice.
Furthermore, this optimization only applies to fixed-function programs;
it does not help modern GLSL-based programs at all. Generally, older
fixed-function programs run fine on modern hardware anyway.
The optimization has existed in some form since the initial commit. When
we rewrote the fragment shader backend, we dropped it for a while. Eric
readded it in commit
eb30820f268608cf451da32de69723036dddbc62 as part of
an attempt to cure a ~1% performance regression caused by converting the
fixed-function fragment shader generation code from Mesa IR to GLSL IR.
However, no performance data was included in the commit message, so it's
unclear whether or not it was successful.
Time has passed, so I decided to re-measure this. Surprisingly,
Eric's OpenArena timedemo actually runs /faster/ after removing this and
the brw_wm_input_sizes atom. On Ivybridge at 1024x768, I measured a
1.39532% +/- 0.91833% increase in FPS (n = 55). On Ironlake, there was

gallivm: do per-pixel cube face selection (finally!!!)
This proved to be tricky, the problem is that after selection/mirroring
we cannot calculate reasonable derivatives (if not all pixels in a quad
end up on the same face the derivatives could get "randomly" exceedingly
large).
However, it is actually quite easy to simply calculate the derivatives
before selection/mirroring and then transform them similar to
the cube coordinates (they only need selection/projection, but not
mirroring as we're not interested in the sign bit, of course). While
there is a tiny bit more work to do (need to calculate derivs for 3
coords instead of 2, and additional selects) it also simplifies things
somewhat for the coord selection itself (as we save some broadcast aos
shuffles, and we don't need to calculate the average vector) - hence if
derivatives aren't needed this should actually be faster.
Also, this has the benefit that this will (trivially) work for explicit
derivatives too, which we completely ignored before that (will be in a
separate commit for better trackability).
Note that while the way for getting rho looks very different, it should
result in "nearly" the same values as before (the "nearly" is only because
before the code would choose the face based on an "average" vector and hence
the derivatives calculated according to this face, where now (for implicit
derivatives) the derivatives are projected on the face selected for the
first (top-left) pixel in a quad, so not necessarly the same face).
The transformation done might not quite be state-of-the-art, calculating
length(dx,dy) as max(dx,dy) certainly isn't neither but this stays the
same as before (that is I think a better transform would _somehow_ take
the "derivative major axis" into account so that derivative changes in
the major axis wouldn't get ignored).
Should solve some accuracy problems with cubemaps (can easily be seen with
the cubemap demo when switching wrapping/filtering), though we still don't
do seamless filtering to fix it completely (so not per-sample but per-pixel
is certainly better than per-quad and already sufficient for accurate
results with nearest tex filter).
As for performance, it seems to be a tiny bit faster too (maybe 3% or so
with cubemap demo). Which I'd have expected with nearest/nearest filtering
where this will be less instructions, but the difference seems to actually
be larger with linear/linear_mipmap_linear where it is slightly more
instructions, probably the code appears less serialized allowing better
scheduling (on a sandy bridge cpu). It actually seems to be now at least
as fast as the old path using a conditional when using 128bit vectors too
(that is probably more a result of testing with a newer cpu though), for now
that old path is still there but unused.
No piglit regressions.
