Previously, we've split things such that mesa core is in libdricore,
exposing the whole Mesa core interface in the global namespace, and the
i965_dri.so code all links against that. Along with polluting application
namespace terribly, it requires extra PLT indirections and prevents LTO.
Instead, we can build all of the driver contents into the same .so with
just a few symbols exposed to be referenced from the actual driver .so
file, allowing LTO and reducing our exposed symbol count massively.
FPS improvement on GLB2.7 with INTEL_NO_HW=1: 2.61061% +/- 1.16957% (n=50)
(without LTO, just the PLT reductions from this commit)
Note that the X Server requires commit
7ecfab47eb221dbb996ea6c033348b8eceaeb893 to successfully load this driver!
v2: Set a global driverAPI variable so loaders don't have to update to
createNewScreen2() (though they may want to for thread safety).
v3: Drop AM_CPPFLAGS addition (Emil pointed out I'd missed some cflags
that would be necessary, though only if we actually relied on them).
v4: Fix install with DESTDIR set.

As we move to megadrivers, we are unable to build multiple drivers with
the same public global symbol per driver (Think an X Server with an intel
and a nouveau driver, and the X Server implementing indirect for both --
we have to actually talk to the right driver). By slipping the
driDriverAPI vtable into the driver's extension list, we can replace the
usage of the global symbol with usage of the loader-dlsym()ed driver
information.
v2: Pull in the hunk to avoid crashing on null driver_extensions. Thanks,

The previous interface relied on a static struct, which meant that the
driver didn't get a chance to edit the struct before the struct got used.
For megadrivers, I want struct specific to the driver being loaded.

Turns out already we have this nice mechanism for providing optional
things from the driver to the loader, and I was going to have to rename
the public global symbol to avoid conflicts when doing megadrivers.
While the former __driConfigOptions is technically loader interface, this
is the only loader that made use of that symbol. Continue paying
attention to it if we can't find the new option, to retain compatibility
with old drivers.

Fixes texture corruption of Weston clients on cairo-glesv2 backend.
Commit 49ed599 introduced the bug.
Corruption occured when glTexSubImage called
intel_texsubimage_tiled_memcpy() with:
x,y=10,9
w,h=7,7
format=GL_ALPHA(0x1906)
type=GL_UNSIGNED_BYTE(0x1401)
gl_format=MESA_FORMAT_A8(0x18)
packing.alignemnt=4
The function miscalculated the source image's stride as w*cpp=7 without
taking into account the packing alignment. The actual stride was 8.

In commit 800610f (i965/fs: Improve accuracy of dFdy() to match
dFdx()) I unrolled the high-accuracy dFdy() computation from a single
SIMD16 instruction to two SIMD8 instructions because of text I found
in the i965 (gen4) PRM saying that instruction compression could not
be used in align16 mode. I couldn't find similar text in later
hardware docs, and I observed problems trying to use instruction
compression on align16 mode on Ivy Bridge, so I assumed that the
restriction still applied and the associated documentation had simply
been lost.
After consultation with the hardware engineers, it turns out this is
not the case. In point of fact, the restriction was dropped in gen5,
re-introduced in Ivy Bridge, and dropped again in Haswell. The reason
I didn't notice this is that in the Ivy Bridge documentation, the
restriction was in a different section, and described using different
language.
Now that we know that the restriction only applies to Gen4 and Ivy
Bridge, we can limit the unrolling to those platforms.
Tested on gen5, gen6, and gen7 (both Ivy Bridge and Haswell).

The layout qualifier identifiers for geometry shader inputs are

And from section 4.3.8.2 (Output Layout Qualifiers)
The layout qualifier identifiers for geometry shader outputs are
layout-qualifier-id

We were erroneously allowing line_strip and triangle_strip to be used
as input qualifiers, and we were allowing lines, lines_adjacency,
triangles, and triangles_adjacency to be used as output qualifiers.

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

else, but this works too.

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.

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
