If glBufferData(), glBufferSubData(0, obj->Size), or similar happens, we
get a new drm_intel_bo for the buffer object, and thus need to re-upload
texture buffer state so we point at the new data.
Fixes the new piglit GL_ARB_texture_buffer_object/data-sync

The new function replaces four old functions: set_fragment/vertex/
geometry/compute_sampler_views().
Note: at this time, it's expected that the 'start' parameter will
always be zero.

Writing a 64-bit register value to memory is sufficiently complicated
that it makes sense to reuse this function rather than duplicating it.
Exposing it outside of gen6_queryobj.c means it needs a more descriptive
function name. It could probably be moved to brw_util.c or somewhere
else, but this works too.

The current callers just want to write a single register, so combining
the register read with a pipeline flush made sense. However, in the
future we'll want to do multiple register reads back to back, and we'll
only want to flush once.

The unit tests added in the previous commits prove some things about the
state of some internal data structures. The most important of these is
that all built-in input and output variables have explicit_location
set. This means that link_invalidate_variable_locations doesn't need to
know the range of non-generic shader inputs or outputs. It can simply
reset location state depending on whether explicit_location is set.
There are two additional assumptions that were already implicit in the
code that comments now document.
- ir_variable::is_unmatched_generic_inout is only used by the linker
when connecting outputs from one shader stage to inputs of another
shader stage.
- Any varying that has explicit_location set must be a built-in. This
will be true until GL_ARB_separate_shader_objects is supported.
As a result, the input_base and output_base parameters to
link_invalidate_variable_locations are no longer necessary, and the code
for resetting locations and setting is_unmatched_generic_inout can be
simplified.

link_invalidate_variable_locations
Validates:
- ir_variable::explicit_location should not be modified.
- If ir_variable::explicit_location is not set, ir_variable::location,
ir_variable::location_frac, and
ir_variable::is_unmatched_generic_inout must be reset to 0.
- If ir_variable::explicit_location is set, ir_variable::location
should not be modified. ir_variable::location_frac, and
ir_variable::is_unmatched_generic_inout must be reset to 0.
Previous unit tests have shown that all non-generic inputs / outputs
have explicit_location set.
v2: Split the link_invalidate_variable_locations interface change out to
a separate patch. Remove the vertex_in_builtin_without_explicit and
vertex_out_builtin_without_explicit tests. There was a lot of good
discussion about this on the mailing list to which I refer the
interested reader. Both changes suggested by Paul.

This will make it easier to unit test this function in successive

- Geometry shader inputs have an explicit location.
- Geometry shader outputs have an explicit location.
- Fragment shader-only varying locations are not used.
- Geometry shader uniforms and system values don't have an explicit
location.
- Geometry shader constants don't have an explicit location and are
read-only.
- No other kinds of geometry variables exist.
It does not verify that an specific variables exist.

Ever since the addition of interface blocks with instance names, we have
had an implicit invariant:
var->type->is_interface() ==
(var->type == var->interface_type)
The odd use of == here is intentional because !var->type->is_interface()
implies var->type != var->interface_type.
Further, if var->type->is_array() is true, we have a related implicit
invariant:
var->type->fields.array->is_interface() ==
(var->type->fields.array == var->interface_type)
However, the ir_variable constructor doesn't maintain either invariant.
That seems kind of silly... and I tripped over it while writing some
other code. This patch makes the constructor do the right thing, and it
introduces some tests to verify that behavior.
v2: Add general-ir-test to .gitignore. Update the description of the
ir_variable invariant for arrays in the commit message. Both suggested
by Paul.

After some discussions about the correct way to update
_mesa_program_state_string, I decided to make a unit test for the

thought. The unit test proves that the code was already correct.

Silence a bunch of MSVC type conversion warnings.
Changed return type of S_FIXED to int32_t (signed). The result

Dead code elimination would get rid of the extra instructions, but
skipping this saves iterations through the optimization loop.
From shader-db:
N Min Max Median Avg Stddev
x 14672 3 16 3 3.1334515 0.59904168
+ 14672 1 16 3 2.8955153 0.77732963
Difference at 95.0% confidence
-0.237936 +/- 0.0158798
-7.59342% +/- 0.506783%
(Student's t, pooled s = 0.693935)
Embarassingly, the classic shadow mapping shader:
void main() { }
used to require three iterations through the optimization loop.
With this patch, it only requires one (which makes no progress).

Previously, Mesa followed the linkage rules outlined in the GLSL
1.20-1.40 specs, which (collectively) said that GLSL versions 1.10 and
1.20 could be linked together, but no other versions could be linked.
In GLSL 4.30, the linkage rules were relaxed so that any two desktop
GLSL versions can be linked together. This change was made because it
reflected the behaviour of nearly all existing implementations (see
Khronos bug 8463). Mesa was one of the few (perhaps the only)
exceptions to prohibit cross-linking of some GLSL versions.
Since the GLSL linkage rules were deliberately relaxed in order to
match the behaviour of existing implementations, it seems appropriate
to relax the rules in Mesa too (even though Mesa doesn't support GLSL
4.30 yet).
Note that linking ES and desktop shaders is still prohibited, as is
linking ES shaders having different GLSL versions.
Fixes piglit tests "shaders/version-mixing {interstage,intrastage}".
