This is a relatively minimal change to adjust all the gallium interfaces
to use bool instead of boolean. I tried to avoid making unrelated
changes inside of drivers to flip boolean -> bool to reduce the risk of
regressions (the compiler will much more easily allow "dirty" values
inside a char-based boolean than a C99 _Bool).

Since logicop_func 0 is PIPE_LOGIOP_CLEAR, we were trigger lowerinng
of logic ops on precompiled shaders, which we don't want to do. Also, this
had the side effect of making shader-db crash, as during this lowering we
would try to read the color format swizzle information from the fragment shader
key that we don't populate in precompiled shaders because right now we only
need it when logic operations are enabled.

We emit code to saturate texture coordinates when using clamp wrapping
mode so if we don't flag the dirty state here we don't get to recompile
the shaders when the wrapping mode changes.

- Do the same when setting sampler views (Eric)
- Use a switch statement instead of an if ladder.

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.

PIPE_CAP_SM3 has always been an odd one out of all our caps. While most
other caps are fine-grained and single-purpose, this cap encode several
features in one. And since OpenGL cares more about single features, it'd
be nice to get rid of this one.
As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.
The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the
drivers, most of who doesn't care a whole lot about DX9 specifically.

PIPE_CAP_PACKED_UNIFORMS conflates several things: Lowering uniforms i/o
at the st level instead of the backend, packing uniforms with no padding

Requiring backends to lower uniforms i/o for !PIPE_CAP_PACKED_UNIFORMS
leads to the driver needing to either link against the type size function
in mesa/st, or duplicating it in the backend. Given that all backends
want this lower-io as far as I can tell, just move it to mesa/st to
resolve the link issue and avoid the driver author needing to understand
st's uniforms layout.

I have v3d allocating enough initial allocation memory that we've been
passing tests without it, but to match kernel behavior more it would be
good to actually exercise the OOM path.
The idea was that we could skip uploading the constant-indexed uniform
data and just upload the uniforms that are variably-indexed. However,
since the VS bin and render shaders may have a different set of uniforms
used, this meant that we had to upload the UBO for each of them. The
first case is generally a fairly small impact (usually the uniform array
is the most space, other than a couple of FSes in shader-db), while the
second is a larger impact: 3DMMES2 was uploading 38k/frame of uniforms
instead of 18k.
Given that the optimization is of dubious value, has a big downside, and
is quite a bit of code, just drop it. No change in shader-db. No change
on 3DMMES2 (n=15).
We'd end up with the constant offset in the uniform stream anyway, since
they're bigger than small immediates. Avoids the extra uniforms and adds
in the shader in favor of just adding once on the CPU.
shader-db:
total instructions in shared programs: 6496865 -> 6494851 (-0.03%)
total uniforms in shared programs: 2119511 -> 2117243 (-0.11%)
I want to reuse this for encoding small constant UBO/SSBO offsets into the
uniform stream to reduce the extra uniform loads and adds for the small
constant offsets.
The glMemoryBarrier() function makes shader memory stores ordered with
respect to things specified by the given bits. Until now, st/mesa has
ignored GL_TEXTURE_UPDATE_BARRIER_BIT and GL_BUFFER_UPDATE_BARRIER_BIT,
saying that drivers should implicitly perform the needed flushing.
This seems like a pretty big assumption to make. Instead, this commit
opts to translate them to new PIPE_BARRIER bits, and adjusts existing
drivers to continue ignoring them (preserving the current behavior).
The i965 driver performs actions on these memory barriers. Shader
memory stores go through a "data cache" which is separate from the
render cache and other read caches (like the texture cache). All
memory barriers need to flush the data cache (to ensure shader memory
stores are visible), and possibly invalidate read caches (to ensure
stale data is no longer visible). The driver implicitly flushes for
most caches, but not for data cache, since ARB_shader_image_load_store
introduced MemoryBarrier() precisely to order these explicitly.
I would like to follow i965's approach in iris, flushing the data cache
on any MemoryBarrier() call, so I need st/mesa to actually call the
pipe->memory_barrier() callback.
Fixes KHR-GL45.shader_image_load_store.advanced-sync-textureUpdate
and Piglit's spec/arb_shader_image_load_store/host-mem-barrier on
the iris driver.

With this patch, tgsi_to_nir will output NIR that is tailored to
the given pipe, by reading its capabilities and adjusting the NIR code
to those capabilities similarly to how glsl_to_nir works.
It also adds an optimization loop that brings the output NIR in line
with what glsl_to_nir outputs. This is necessary for the same reason
why glsl_to_nir has its own optimization loop: currently not every
driver does these optimizations yet.
For uses which cannot pass a pipe_screen we also keep a variant
called tgsi_to_nir_noscreen which keeps the old behavior.
