freedreno/a6xx: move ubwc clear to blitter

Avoid having to mmap() unnecessarily by moving UBWC clear/init to

Because we don't have a context when the bo is allocated, we need to

panfrost: Remove postfix parameter from UBO upload

Need to signal push constants via a side channel. I tried to disentangle
this code, but there are a number of stacked issues here:

* We need to upload sysvals. Currently we prefix UBO #0 with sysvals,
  but this requires a memcpy() of the entire contents of UBO #0. We
  could create a synthetic UBO instead with sysvals at the end.

* We want to push uniforms/sysvals. Currently we push UBO #0 as much as
  we can, which pushes sysvals automatically by point 1.

* We want to optimize out f2f16(uniform). We don't currently handle
  this.

* We want to optimize out uniform-on-uniform/constant operations. Mesa
  doesn't currently have good support for this.

The real solution will look something like:

* Create a separate UBO for sysvals.

* Let the compiler allocate push constant space as it sees fit ("copy
  word 12:15 of UBO 1 to word 2:3 of push constant space, as fp16").

* Somehow handle uniform folding when NIR gains support.

For now, let's not block the depostfixening.

nir/lower_vec_to_movs: Convert to use nir_shader_instructions_pass().

Less pass code, less indenting, should be the same perf.

nir: Add a helper for general instruction-modifying passes.

The nir_shader_lower_instructions() is really nice, but it's only for SSA
operations, and sometimes you want something more general.  I've put it in
nir_builder.h so it can be inlined and retain the same performance
characteristics we're used to in our lowering passes even in the absence
of LTO.

nir/opt_copy_prop_vars: Quiet valgrind warning about overlapping memcpy.

The warning is kind of silly:

Test case 'dEQP-GLES2.functional.shaders.indexing.tmp_array.vec3_const_write_static_read_vertex'..
==1874780== Source and destination overlap in memcpy(0xa261690, 0xa261690, 160)
==1874780==    at 0x484D498: __GI_memcpy (vg_replace_strmem.c:1037)
==1874780==    by 0x596FC07: copy_entry_remove (nir_opt_copy_prop_vars.c:296)

The "memcpy is undefined if they overlap" thing is surely meant to be
"memcpy with *partial* overlap is undefined", but let's keep anyone else
from having to debug this.

iris: Drop stale syncobj references in fence_server_sync

When calling glWaitSync (fence_server_sync), we added dependencies
in all batches (render and compute) on existing work.  Even if
applications don't use compute at all, they theoretically could,
so we record that the compute batch depends on the render batch.

But if the application truly doesn't use compute, or rarely uses
it, we ended up recording dependencies on _all_ previous render
batches, racking up a massive list of syncobjs.  Not only is this
pointless, it also meant that we never allowed the kernel to free
the underlying i915_request objects.

There are a number of solutions to this problem, but for now, we
take a simple one: when recording a new syncobj dependency, we
walk the list and see if any of them have already passed.  If so,
that dependency has been fulfilled.  We no longer need to track it,
and can simply drop it from the list, unreferencing the syncobj.

Android's SurfaceFlinger in particular was hitting this issue,
as it uses glWaitSync, doesn't typically use compute shaders,
and runs for long durations.

Thanks to Yang A Shi <yang.a.shi@intel.com> and
Kefei Yao <kefei.yao@intel.com> for their excellent work in
tracking down this issue!

clearer why.
