We have been relying on NIR's gather info pass for this
but it is not safe unless we are certain we are always
calling it after any other pass that may emit a control
barrier.
As it stands, nir_zero_initialize_shared_memory can emit a
control barrier and we don't call the gather info pass after
it, which is problematic. The only reason this is not really
a problem right now is because for non-scoped barriers (which
is what we currently use) it doesn't emit a scoped barrier, just
a regular memory barrier (which is probably a bug in the pass!),
but as soon as we move to scoped barriers, this is going
to be a problem, since we need to know when we emit a control
barrier to ensure supergroup calculations prevent deadlocks at
the barrier op.

Rather than translate piles of discrete memory_barrier/control_barrier
instructions, translate the unified scoped_barrier which maps almost directly to
SPIR-V's barrier. Yes, this means I cheated off vtn for the implementation.
v2: Use existing scope translation.

If two threads deserialize the raw object at the same time, the
refcount could be more than 1 temporarily.
This can be reproduced with Granite during the multi-threaded pipeline
cache pre-warm on startup, and also with Dota2.

There's little point in open-coding this, when we already have a helper
for it.
This adds an fsat to both code-paths. Not sure if that's good or bad, or
if it even matters at all.

nir_ffma_imm has several variants that allows specific arguments to be

When doing nir_fsub(b, x, imm), we can negate the immediate value, and
replace the fsub with nir_fadd_imm() and get the same result. This makes
the code a bit shorter and easier to read.

This simplifies things a bit. Note that in some cases, the arguments are
swapped, because multiplications are commutative, and nir_fmul_imm only
allows the second operand to be an immediate.

Vulkan says you can do things like image resolves or blits on transfer
queues, but D3D only allows literal copies. We could try to emulate
a Vulkan transfer-only queue backed by multiple D3D queues, where we
use the copy queue when possible but fall back to compute when needed,
but let's wait until there's a good reason to do that...

Forcing bindless on is nice for apps that don't use EXT_descriptor_indexing,
but for the CTS, whenever EXT_descriptor_indexing is supported, it's used.
To be able to more thoroughly test the not-bindless path, add a debug flag
to turn it off.

pvr_gpu_upload() can't be used in the case of pvr_gpu_upload_usc() as it expects
the source and destination buffers to be the same size. This isn't the case
because pvr_gpu_upload_usc() adds some padding bytes to the size passed in by
the caller.
