Meta's GenerateMipmap implementation binds the same image for both
sampling and rendering - but it samples from one miplevel while
rendering the next. This is a false self-dependency, and there's
no need to disable auxiliary buffers in this case. In fact, we really
want to leave it enabled so the new miplevels gain color compression.
Thankfully, the texture object's _MaxLevel is always one shy of the
miplevel being rendered. So we can simply check if irb->mt_level is
overlaps with the texture's defined levels. If not, there's no self-
dependency and we can leave the auxiliary buffers enabled.
Fixes a performance regression in GFXBench4 Car Chase, which apparently
calls glGenerateMipmap() on every frame.

This effectively exports intel_miptree_prepare_texture_slices() as
intel_miptree_prepare_texture(). The hope is to avoid resolves for
when using texture views that access a subset of the levels/layers.
For now, we pass the same arguments to separate the mechanical change
from the one that actually modifies our behavior.

The restriction is supposed to apply if the width *field* is >= 8192,
meaning the actual width *value* is >= 8193.

Commit a73116ecc6 tried to make add_barrier_deps()
walk to the next barrier, and stop. To accomplish that, it added an
is_barrier flag. Unfortunately, this only works half of the time.
The issue is that add_barrier_deps() walks both backward (to the
previous barrier), and forward (to the next barrier). It also sets
is_barrier. Assuming that we're processing instructions in forward
order, this means that is_barrier will be set for previous instructions,
but not future ones. So we'll never see it, and walk further than we
need to.

This eliminates a layer of wrapping, and makes a backend_instruction
sufficient. The downside is that it exposes 'eot' to the vec4 backend,
which it doesn't need, but can basically happily ignore.

We only need to add a check to validate output locations here. For
inputs with invalid locations we will fail to link when we can't
find a matching output in the same (invalid) location.

When we have up to 16 FS inputs, the SF unit will reorder our inputs
to be consecutive, however, when we have more than 16 we need to
to read our inputs from the URB exactly as they have been
output from the previous stage. This means that for SSO we have to
consider if we have URB padding due to unused input locations.
Specifically, this affects gen9 active components programming, since
for things to work in scenarios with over 16 inputs that have padded
regions we need to ensure that we program active components for the
padded regions too. If we don't do this the hardware won't read
the URB properly for inputs located after padded regions.
Found empirically.

We only want to scare the user away from causing a GPU stall for mapping

“Saints Row: Gat out of Hell” benefits from this on slower CPUs in that
usage spikes on individual cores are avoided, which in turn makes it harder
to hit a bug which causes broken audio and the game to hang on exit.
“Saints Row IV” appears to be fine either way, but also exhibits the audio
breakage bug: glthread is therefore being enabled on the grounds that it should
make it a little harder to hit that bug.
