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
no statistically significant difference (n = 37).

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.

i965: Reduce code duplication in handling of depth, stencil, and HiZ.
This patch consolidates duplicate code in the brw_depthbuffer and
gen7_depthbuffer state atoms. Previously, these state atoms contained
5 chunks of code for emitting the _3DSTATE_DEPTH_BUFFER packet (3 for
Gen4-6 and 2 for Gen7). Also a lot of logic for determining the
appropriate buffer setup was duplicated between the Gen4-6 and Gen7
functions.
This refactor splits the code into three separate functions:
brw_emit_depthbuffer(), which determines the appropriate buffer setup
in a mostly generation-independent way, brw_emit_depth_stencil_hiz(),
which emits the appropriate state packets for Gen4-6, and
gen7_emit_depth_stencil_hiz(), which emits the appropriate state
packets for Gen7.
Tested using Piglit on Gen5-7 (no regressions).
v2: Re-word some comments. Fix an assertion that incorrectly
prohibited packed depth/stencil formats on Gen6 (these are allowed
provided that HiZ is disabled).

Mesa constant-folds built-in functions by using a miniature GLSL

ir_function_signature::constant_expression_evaluate_expression_list()).
This interpreter had a bug in its handling of array indexing, which
caused expressions like "m[i][j]" (where m is a matrix) to be handled
incorrectly. Specifically, it incorrectly treated j as indexing into
the whole matrix (rather than indexing just into the vector m[i]); as
a result the offset computed for m[i] was lost and m[i][j] was treated
as m[j][0].

There are definitely a couple of differences - the old implementation
had unspecified(?) rounding behavior, and could at least in theory
construct Inf values out of NaNs. NaNs and Infs should now always be
properly propagated, and rounding behavior is now towards zero
(note this means too large but non-Infinity values get propagated to max
representable value, not Infinity).
The implementation will definitely not match util code, however (which
does nearest rounding, which also means too large values will get
propagated to Infinity).
