spirv: Clean up OpSignBitSet

For some reason, we were doing a signed shift vectors and an unsigned
shift for scalars.  We then plug it into i2b so it should make no
difference whatsoever.  The fact that we're doing different things for
vectors vs. scalars is bonkers.  Let's simplify the code a bit.

spirv: Simplify our handling of NonUniform

The original implementation of SPV_EXT_descriptor_indexing was extremely
paranoid about the NonUniform qualifier, trying to fetch it from every
possible location and propagate it through access chains etc.  However,
the Vulkan spec is quite nice to us on this and has very strict rules
for where the NonUniform decoration has to be placed.  For image and
texture operations, we can search for the decoration on the spot when we
process the image or texture op.  For pointers, we continue putting it
on the pointer but we don't bother trying to do anything silly like
propagate it through casts.

radv: Add thread for timeline syncobj submission.

For cross-process timelines we have to have a thread to wait
till the requested points become available.

The functions actually dealing with timeline semaphores stubbed out, to
implement in the next patch. As such the thread code shouldn't trigger
yet.

The core idea is that we still use the refcount mechanism that we use with
emulated timelines, though the native timeline syncobj don't participate
in the refcounting. This way we keep the ordering of submission in a queue
as each submission is also blocked by its predecessor.

Where we change behavior is when the number of blockers reaches 0. In the
new code we check if we need to wait for the timeline semaphores to
be available and if so we won't execute the submission immediately but
pass it to the submission thread.

radv/winsys: Add binary syncobj ABI changes for timeline semaphores.

To facilitate cross-process timeline semaphores we have to deal with
the fact that the syncobj signal operation might be submitted a
small finite time after the wait operation.

For that we start using DRM_SYNCOBJ_WAIT_FLAGS_WAIT_FOR_SUBMIT during
the wait operation so we properly wait instead of returning an error.

Furthermore, to make this effective for syncobjs that get reused we
actually have to reset them after the wait. Otherwise the wait before
submit would get the previous fence instead of waiting for the new
thing to submit.

The obvious choice, resetting the syncobj after the CS submission
has 2 issues though:

1) If the same semaphore is used for wait and signal we can't reset it.
   This is solvable by only resetting the semaphores that are not in the
   signal list.
2) The submitted work might be complete before we get to resetting the
   syncobj. If there is a cycle of submissions that signals it again and
   finishes before we get to the reset we are screwed.

Solution:
Copy the fence into a new syncobj and reset the old syncobj before
submission. Yes I know it is more syscalls :( At least I reduced the
alloc/free overhead by keeping a cache of temporary syncobjs.

This also introduces a syncobj_reset_count as we don't want to reset
syncobjs that are part of an emulated timeline semaphore. (yes, if
the kernel supports timeline syncobjs we should use those instead,
but those still need to be implemented and if we depend on them in
this patch ordering dependencies get hard ...)

intel/ir/gen12+: Work around FS performance regressions due to SIMD32 discard divergence.

This avoids some performance regressions on Gen12 platforms caused by
SIMD32 fragment shaders reported in titles like Dota2, TF2, Xonotic,
and GFXBench5 Car Chase and Aztec Ruins.

The most obvious pattern in the regressing shaders I identified among
these workloads is that they all had non-uniform discard statements,
which are handled rather optimistically by the current IR analysis
pass: No penalty is currently applied to the SIMD32 variant of the
shader in the form of differing branching weights like we do for other
control flow instructions in order to account for the greater
likelihood of divergence of a SIMD32 shader.

Simply changing that by giving the same treatment to discard
statements as we give to other branching instructions seemed to hurt
more than it helped on platforms earlier than Gen12, since it reversed
most of the improvement obtained from SIMD32 fragment shaders in
Manhattan for no measurable benefit in other workloads (Manhattan has
a handful of shaders with statically non-uniform discard statements
which actually perform better in SIMD32 mode due to their approximate
dynamic uniformity).  For that reason this change is applied to Gen12+
platforms only.

I've been running a number of tests trying to understand the
difference in behavior between Gen12 and earlier platforms, and most
of the evidence I've gathered seems to point at EU fusion being the
culprit: Unlike previous generations, on Gen12 EUs are arranged in
pairs which execute instructions in lockstep, giving an effective warp
size of 64 threads in SIMD32 mode, which seems to increase the
likelihood for control flow divergence in some of the affected shaders
significantly.

i915: Remove a bunch of default handling of pipe caps.

u_screen will return 0 for all of these, which means that this is one
less driver to see in git grep when I'm checking who exposes a cap.
The exception is the texel/gather offsets and stream output
components, which will not be exposed since we don't expose the
corresponding GLSL version.
