The next two commits modify the destination regioning in a way that,
which still correct, trigger assertion failures if we try to fix the
regioning here.
Broadcast gets lowered in brw_eu_emit. For the purposes of region
restrictions, let's assume that the final code emission will do the
right thing. Doing a bunch of shuffling here is only going to make a
mess of things.

tracing_ctx is always non-NULL in issue_fragment_jobs. Check
tracing_ctx->enabled instead. This fixes GPU faults when the desc
ringbuf wraps.

Caterina already implemented this in ed64fa034b ("panvk: never prefer or
require dedicated allocation for buffers") and dbdaefb6ed ("panvk: never
require dedicated allocation for images"), so let's flip the switch.
We pass 4505 of the CTS tests, and fail a single one. Let's mark that
one as an expected failure and move on for now.

The spec mandates that if the program object isn't created from IL, it
should not touch the buffer. Passing an empty slice would achieve that,
but it's better to be explicit here.

The old way was quite annoying as it required to create a Vec to even get
the size of the result causing needless computations.
This also meant that copying into the result buffer always required to go
through a byte Vec even though we could just do the copy directly.
The main idea here is that instead of returning the result, we simply call
into a write function giving us more flexibility here.
Potentially this will also allow us to add overloads for Iterators or to
even use closures in case the size calculation is cheaper than creating
the value just to get the size.

Since the leaf node pass doesn't run for updates, leaf_node_count never
got set. This resulted in updates always running on 0 leaves (i.e. being
no-ops).

Backward inter-shader code motion left dead output stores in the producer
in rare cases. Those dead stores would then make their way into drivers
and hw.

If input_value, index, index1 or index2 is an input, here are examples of
code that this commit moves from consumers to producers:
* input_value * uniform_array[index]
* uniform_array[index]
* ubo[0].array[index]
* ubo[index].var
* ubo[index1].array[index2]
If the array index is computed from an input, it must be flat or convergent
within a primitive to be moved. If the array index is not an input, it must
be a uniform expression.
dEQP-GLES31.functional.shaders.opaque_type_indexing.ubo.dynamically_uniform_fragment
has UBO indexing that is moved to the producer by this.

They are a maintainenance burden since they would need changes to
support more instruction types that nir_opt_varyings will be able to
move between shaders, and they are almost identical to
default_varying_estimate_instr_cost, so just use that.
The cost threshold is adjusted for AMD because
default_varying_estimate_instr_cost is slightly different.

Holes due to indirectly-indexed inputs were ignored, making the compaction
worse when such inputs were present alongside convergent inputs.
