We just need to add a write dep if rf0 is written implicitly.
Note that we don't need to check if we have accumulators when checking
for r3/r4/r5, as v3d_qpu_writes_rX would return false for hw version
that doesn't have accumulators.

Note that what we do is to just return false on the favor/select accum
methods. We could just avoid to call them, but as the select is called
more than once, it is just easier this way.

At this point it just tidy up a little the alu_instr structure.
But also serves to prepare the structure for new changes, as 7.x uses
raddr instead of mux, and it is just easier to add the raddr to the
new input structure.

small_imm_a, small_imm_c and small_imm_d added on top of the already
existing small_imm_b, as V3D 7.1 defines 4 small immediates, tied to
the 4 raddr. Note that this is only the definition, and just a inst
validation rule to check that are not used before v71. Any real use is
still pending.

Current small_imm is associated with the "B" read address.
We do this change in advance for v71 support, where we will have 4
different small_imm (a/b/c/d), so we start with a renaming.

Having this pointer in the key is undesirable since it makes
copying keys difficult and error prone (as seen in previous
patches), also, it is only there for convenience and we don't
strictly need it (in fact the vulkan driver doesn't use it at
all), so let's just get rid of it so our v3d_key is fully
static.

Our shader key includes a void pointer that we can't just memcmp,
so add helpers that allow us toget the 'static' portion and size
of a key. We will use this to fix up the shader cache in v3d in
a later patch.

We already renamed the type, we just need to rename the enum and the

We could add a nir_def_bit_size() helper but we use ->bit_size about 3x

There's no legacy register support so we ncessarily write a contiguous vector.
In other words, the write_mask is of the form `(1 << x) - 1`. Meanwhile this
code asserts the write mask is of the form (1 << x)`. Putting it together the
write mask is necessarily always 0x1, writing out a single scalar.
