Instead of just having a bool status for the failure, there is now an
enum so that the compilation can report a more detailed status.
Currently this is only used to report whether the failure was due to

nir/schedule: Add an option for a fallback scheduling algorithm

The current scheduling algorithm favors parallelism a bit too
aggressively and sometimes generates shaders that fail register
allocation. This happens even if the threshold is set to zero to force
it to always use the CSR instruction choosing algorithm.

This patch adds an option to use an even more aggressive fallback that
just always picks the instruction with the shortest maximum delay in the
hope that that will generate the least register pressure. The intention
is to use this as a last resort after register allocation fails in order
to at least have a working shader.

spirv: Rework our handling of images and samplers

Previously, objects of type OpTypeImage or OpTypeSampler were treated as
vtn_pointers and objects of type OpTypeSampledImage were a special-use
vtn_sampled_image struct.  This commit changes that so that all of those
objects are stored in vtn_ssa_values.  Each of images, samplers, and
sampled images, are stored as a scalar or vector nir_ssa_def whose
components are NIR deref values.  We now use vtn_type_get_nir_type to
re-resolve those as-needed into GLSL sampler types for NIR.

This simplification has a number of benefits:

 1. We can git rid of the rest of our special-cases for handling images
    and samplers in function arguments.  Now that they're treated as
    structs at the glsl_type level, the generic paths can handle images
    and samplers.

 2. We can now construct composite values containing images and samplers
    internally.  It's unclear from the SPIR-V spec whether or not this
    is allowed and it's not a pattern that GLSLang currently generates
    thanks to GLSL rules.  However, if we do start seeing SPIR-V that
    contains such composites, we should now be able to handle it.

 3. SPIR-V OpNull and OpUndef instructions can now create samplers,
    images, and sampled images.  The NIR generated won't likely be fully
    valid but, given a NIR pass to do something sensible, it should be a
    thing we can compile.

For cross-process timelines we have to have a thread to wait

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

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

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 ...)

nir/ lower_int_to_float: Handle umax and umin

8e1b75b3 introduced umax/umin in order to lower iand/ior for (n)eq zero.
That breaks the lower_int_to_float pass, because umax and umin weren't
handled there.

Tested with lima. The other users of nir_lower_int_to_float
(etnaviv, freedreno) should also have that issue.

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.
