gallivm: minor rho calculation optimization for 1 or 3 coords
Using a different packing for the single coord case should save a shuffle.
Plus some minor style fixes.

gallivm: use f16c hw support for float->half and half->float conversion
Should be way faster of course on cpus supporting this (includes AMD
Bulldozer and Jaguar cores, Intel Ivy Bridge and up (except budget models)).
Passes piglit fbo-blending-formats GL_ARB_texture_float -auto on Ivy Bridge.

draw/llvmpipe: allow independent so attachments to the vs
When geometry shaders are present, one needs to be able to create
an empty geometry shader with stream output that needs to be
resolved later and attached to the currently bound vertex shader.
Lets add support for it to llvmpipe and draw. draw allows attaching
independent stream output info to any vertex shader and llvmpipe
resolves at draw time which vertex shader the given empty geometry
shader should be linked to.

st/mesa: fix bitmap,drawpix,drawtex for PIPE_CAP_TGSI_TEXCOORD
NOTE: Changed the semantic index for the drawtex coordinate to
be the texture unit index instead of always 0.
Not sure if this is correct but since the value seems to depend
on the unit it would make sense to use different varying slots.
nvc0: use fence to check state of queries that don't write sequence
This still isn't optimal, since the fence will signal a bit late,
but better than checking on the bo, which may never be ready if it
is shared (which is likely).
gallium/hud: add support for PIPE_QUERY_PIPELINE_STATISTICS
Also, renamed "pixels-rendered" to "samples-passed" because the
occlusion counter increments even if colour and depth writes are
disabled, or (on some implementations) for killed fragments that
passed the depth test when PS early_fragment_tests is set.
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).

Revert "glsl: Replace constant-index vector array accesses with swizzles"
This reverts commit dbf94d105a48b7aafb2c8cf64d8b4392d87efea1, which
was working around a bug in the handling of array indexing when
constant folding built-in functions. Now that the constant folding
bug has been fixed, the workaround is no longer needed.
glsl: Fix array indexing when constant folding built-in functions.
Mesa constant-folds built-in functions by using a miniature GLSL
interpreter (see
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].
Fixes piglit tests inverse-mat[234].{vert,frag}.
NOTE: This is a candidate for the 9.1 and 9.0 branches.

gallivm: bring back optimized but incorrect float to smallfloat optimizations
Conceptually the same as previously done in float_to_half.
Should cut down number of instructions from 14 to 10 or so, but
will promote some NaNs to Infs, so it's disabled.
It gets a bit tricky though handling all the cases correctly...
Passes basic tests either way (though there are no tests testing special
cases, but some manual tests injecting them seemed promising).

gallivm: consolidate code for float-to-half and float-to-packed conversion.
This replaces the existing float-to-half implementation.
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).
Also fix a bogus round mask probably leading to rounding bugs...
v2: fix a logic bug in handling infs/nans.
