Binding comparison is used to determine the block the uniform is part
of. Note that to do the binding comparison we need the information in
UniformBlocks[] and ShaderStorageBlocks[] to be available, so we have
to call gl_nir_link_uniform_blocks() before linking the uniforms.

This was probably not caught before because no supported test was
exercising the flrp lowering with other bit size different than 32.
With the arrival of VK_KHR_shader_float_controls we will have some of
those and, unless we keep the bit size, we will end with something
like:
../src/compiler/nir/nir_builder.h:420: nir_builder_alu_instr_finish_and_insert: Assertion `src_bit_size == bit_size' failed.

This includes metadata as well. On GFX10, we have to invalidate
the L2 metadata cache when shaders read DCC.
Note that we still have to implement GFX10 coherency by
introducing INV_L2_METATADA but for now just flush L2.
This fixes a corruption with DCC and Talos.

This allows to remove a mov of 1/-1, as it is implicit with the
operation.
As with atomic inc/dec/add, usual shader-db set doesn't include any
GLES shader using it. So using as workaround vk-gl-cts shaders, we get
this:
total instructions in shared programs: 1217013 -> 1217006 (<.01%)
instructions in affected programs: 53 -> 46 (-13.21%)

HURT: 0
One of the helped shader went from 40 to 34 instructions.

Among other things, this avoid the need of loading 1/-1 constants (so
one less operation).
The removed comment suggest the option of adding support on NIR for
inc/dec. Intel just uses an auxiliar method to get which hw operation
is needed, so no lowering is needed. And at the same time, being so
small, seems unreasonable to try to add a general one on NIR
itself. It is more easy to just adapt the method here (that is what
the patch does right now).
It is worth to note that we are not getting any change on shader-db
stats because all those methods are used on the usual shader-db set
with shaders needing GLSL > 4.2. In general there aren't too many GLSL
ES 3.1 tests.
As an alternative, we captured the GLES3/GLSL31/GLS32 used on
vk-gl-cts, even if that is not a real life usage of shaders. With
those we get the following:
total instructions in shared programs: 1217022 -> 1217013 (<.01%)
instructions in affected programs: 117 -> 108 (-7.69%)
helped: 6
HURT: 0
helped stats (abs) min: 1 max: 2 x̄: 1.50 x̃: 1
helped stats (rel) min: 3.57% max: 10.00% x̄: 8.09% x̃: 9.09%
95% mean confidence interval for instructions value: -2.07 -0.93
95% mean confidence interval for instructions %-change: -10.54% -5.64%
Instructions are helped.
Note that the shaders helped are really low because most of the
vk-gl-cts tests using AtomicInc/Dec/Add are mostly used on compute
shaders. Although right now there is a branch around with CS support,
the usual is doing the stats against master.

They are already defined, although is a slightly different format on
the generated packet headers, so it was needed to change how it is
used on nir_to_vir.
In addition to allow to remove some duplicated headers, it will allow
to define just one get_op_for_atomic_add aux method later to support
using inc/dec instead of add of 1/-1.

This implements support for OpenGL logic operations by emitting code to read
from the TLB if needed and blending the fragment output accordingly. It is
similar to VC4's blend lowering pass, but exclusive to logic operations, since
blending is otherwise supported in hardware.
The pass doesn't handle MSAA targets yet.
Fixes the following piglit tests:
spec/!opengl 1.0/gl-1.0-logicop/*
spec/!opengl 1.1/gl-1.1-xor
spec/!opengl 1.1/gl-1.1-xor-copypixels
It also fixes text cursor rendering in Libreoffice with the GTK+2 theme, which
is rendered via glamor using the XOR logic operation.

Until now we have always been emitting our scoreboard locks on the last thread
switch to improve parallelism. We did this by emitting our last thread switch
right before our tlb writes at the very end of the program, where we know that
we are outside control flow.
Unfortunately, this strategy is not valid when we have tlb color reads too, as
these will happen before this point in the program and can happen inside
control flow.
To fix this we always emit a thread switch before the first tlb load and if we
see additional thread switches after that point, we change the strategy to lock
on the first thread switch.
v2: change the solution so it is expected to work in more scenarios (Eric).
