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.

Usually the register demand before an instruction would be considered part
of the previous instruction, since it's not greater than the register
demand for that previous instruction. Except, it can be greater in the
case of an definition fixed to a non-killed operand: the RA needs to
reserve space between the two instructions for the definition (containing
a copy of the operand).

We need to do 3 things to accomplish this :
1. make all the register access consider the maximal case when
unknown at compile time
2. move the clamping of load_per_vertex_input prior to lowering
nir_intrinsic_load_patch_vertices_in (in the dynamic cases, the
clamping will use the nir_intrinsic_load_patch_vertices_in to
clamp), meaning clamping using derefs rather than lowered
nir_intrinsic_load_per_vertex_input
3. in the known cases, lower nir_intrinsic_load_patch_vertices_in
in NIR (so that the clamped elements still be vectorized to the
smallest number of URB read messages)

nir_registers are only supposed to be used temporarily. They may be created by a
producer, but then must be immediately lowered prior to optimizing the produced
shader. They may be created internally by an optimization pass that doesn't want
to deal with phis, but that pass needs to lower them back to phis immediately.
Finally they may be created when going out-of-SSA if a backend chooses, but that
has to happen late.
Regardless, there should be no case where a backend sees a shader that comes in
with nir_registers needing to be lowered. The two frontend producers of
registers (tgsi_to_nir and mesa/st) both call nir_lower_regs_to_ssa to clean up
as they should. Some backend (like intel) already depend on this behaviour.
There's no need for other backends to call nir_lower_regs_to_ssa too.
Drop the pointless calls as a baby step towards replacing nir_register.

Also this value is not the actual aperture in i915, it actualy is the

So here replacing it by the sram size, something that will vary

This fix some tests with Xe KMD, as it is not setting aperture_bytes.
And will not do that as there is no UAPI to fetch this information

Right now if we fail to register allocate, we return the qpu_insts
that we had at that point, even if the driver can't really use it.
Also v3dv_pipeline was already assuming that it would return NULL on
failure, returning VK_ERROR_UNKNOWN on that case.
This allows CTS tests with a lot of pressure, that regress now and
then to not being able to allocate, to finish with an error, instead
of blocking forever. For example:
