Unless an algebraic pass does something silly where it inserts something

instruction from a ffma to an add.  This, in turn, *decreases* register
pressure in one part of the program causing it to fail to register allocate
and spill.  Given the overwhelmingly positive results in other shaders and

i965: Handle scratch accesses where reladdr also points to scratch space

This is a problem when we have IR like this:

(array_ref (var_ref temps) (swiz x (expression ivec4 bitcast_f2i
   (swiz xxxx (array_ref (var_ref temps) (constant int (2)) ) )) )) ) )

where we are indexing an array with the result of an expression that
accesses the same array.

In this scenario, temps will be moved to scratch space and we will need
to add scratch reads/writes for all accesses to temps, however, the
current implementation does not consider the case where a reladdr pointer
(obtained by indexing into temps trough a expression) points to a register
that is also stored in scratch space (as in this case, where the expression
used to index temps access temps[2]), and thus, requires a scratch read
before it is accessed.

v2 (Francisco Jerez):
 - Handle also recursive reladdr addressing.
 - Do not memcpy dst_reg into src_reg when rewriting reladdr.

v3 (Francisco Jerez):
 - Reduce complexity by moving recursive reladdr scratch access handling
   to a separate recursive function.
 - Do not skip demoting reladdr index registers to scratch space if the
   top level GRF has already been visited.

v4 (Francisco Jerez)

 - Simplify code by making emit_resolve_reladdr return a register with
   the original src data except for reg, reg_offset and reladdr.

gallivm: implement TG4 for ARB_texture_gather

This is quite trivial, essentially just follow all the same code you'd
use with linear min/mag (and no mip) filter, then just skip the filtering
after looking up the texels in favor of direct assignment of the right channel
to the result. (This is though not true for the multi-offset version if we'd
want to support it - for this would probably need to do something along the
lines of 4x nearest sampling due to the necessity of doing coord wrapping
individually per texel.)
Supports multi-channel formats.
From the SM5 gather cap bit, should support non-constant offsets, plus shadow
comparisons (the former untested), but not component selection (should be
easy to implement but all this stuff is not really exposable anyway for now).

gallivm: simplify sampler interface

This has got a bit out of control with more and more parameters added.
Worse, whenever something in there changes all callees have to be updated
for that, even though they don't really do much with any parameter in there
except pass it on to the actual sampling function.
Hence simply put almost everything into a struct. Also instead of relying
on some arguments being NULL, be explicit and set this in a key (which is
just reused for function generation for simplicity). (The code still relies
on them being NULL in the end for now.)
Technically there is a minimal functional change here for shadow sampling:
if shadow sampling is done is now determined explicitly by the texture
function (either sample_c or the gl-style tex func inherit this from target)
instead of the static texture state. These two should always match, however.

glsl: fail when a shader's input var has not an equivalent out var in previous

GLSL ES 3.00 spec, 4.3.10 (Linking of Vertex Outputs and Fragment Inputs),
page 45 says the following:

"The type of vertex outputs and fragment input with the same name must match,
otherwise the link command will fail. The precision does not need to match.
Only those fragment inputs statically used (i.e. read) in the fragment shader
must be declared as outputs in the vertex shader; declaring superfluous vertex
shader outputs is permissible."
[...]
"The term static use means that after preprocessing the shader includes at
least one statement that accesses the input or output, even if that statement
is never actually executed."

And it includes a table with all the possibilities.

Similar table or content is present in other GLSL specs: GLSL 4.40, GLSL 1.50,
etc but for more stages (vertex and geometry shaders, etc).

This patch detects that case and returns a link error. It fixes the following
dEQP test:

  dEQP-GLES3.functional.shaders.linkage.varying.rules.illegal_usage_1

However, it adds a new regression in piglit because the test hasn't a
vertex shader and it checks the link status.

bin/glslparsertest \
tests/spec/glsl-1.50/compiler/gs-also-uses-smooth-flat-noperspective.geom pass \
1.50 --check-link

This piglit test is wrong according to the spec wording above, so if this patch
is merged it should be updated.
