The resource declarations are module-wide, but the resource handles
are function-local. A future change will add multi-function support,
but requires these handles to be potentially emitted multiple times.
The alloca used for scratch is also function-local.
This is the same pattern that the DXBC to DXIL converter uses.

In the case of two vars being packed into the same register / location,
they'll still get unique driver_location, which is what we need.
This does require some tweaks to stream output handling, which also needs to
produce the varying index.

On platforms where we don't support 64 bit instructions we shouldn't
pass such instructions for the code generator to lower into supported
instructions, because this makes their execution pipeline
unpredictable to the scoreboard lowering pass on XeHP+ platforms.
We really should be reducing all these 64 bit instructions before code
generation, so here we add an assert to help us catch and fix these
cases more easily.

One of the two SHUFFLE implementations wasn't taking into account the
destination stride at all, and the other (more commonly used) one was
taking it into account incorrectly since brw_reg::hstride represents
the stride logarithmically, so we need to use a left-shift operator
instead of product. Found by inspection.

This adds some generic infrastructure that allows splitting any
instruction into a number of instructions of a smaller legal execution
type. This is meant to replace several instances of handcrafted 64bit
type lowering done manually in the code generator, which is rather
error-prone, prevents scheduling of the lowered instructions, and
makes them invisible to the SWSB pass on Gfx12+ platforms, which will
become especially problematic on Gfx12.5+ since the EUs introduce
multiple asynchronous execution pipelines which the SWSB pass needs to
be able to synchronize to one another, so it's critical for the real
execution type of the instruction to be visible to the SWSB pass.

Right now the execution type lowering functionality of this pass
assumes that an integer type of the original bit size is always
acceptable, however we'll want more complex behavior than that in
order to leverage this pass to automate the lowering of unsupported
64-bit operations into multiple 32-bit operations.
In order to do that calculate the closest legal execution type from a
new helper function, and take advantage of that function from the
has_invalid_exec_type() helper, along the lines of other
lower_regioning() helpers structured as a pair of has_invalid_foo() +
required_foo() functions.
This shouldn't have any functional changes.

Previously the software scoreboard structure would drop previous
dependencies for a given register and replace them with the most
recent one for the same register when a new instruction (or set of
instructions) is processed. This worked correctly on the Gfx12LP
platforms this code was originally designed for, because a repeated
dependency on the same register would either require the second
instruction to synchronize against the first (so the first dependency
could be disregarded from that point on) *or* require the dependency
to be RaR and in-order, which allows the synchronization to be
optimized out (the first dependency could still be disregarded as
well, since the pipeline is in-order). However the latter assumption
will break on upcoming Gfx12HP platforms, because they have multiple
asynchronous FPU pipelines, so whenever we hit a RaR dependency we
need to propagate forward both dependencies, since the order in which
both reads will complete is not guaranteed by the hardware in cases
where they occur from different asynchronous pipelines.
Note that this dependency propagation change requires us to change the
definition of dependency::done as well, since that constant is defined
to discard any previous dependency information when used as argument
for shadow().

As explained at the header of the lowering:
"Once this pass is done, the color write will either have one
component (for single sample) with packed argb8888, or 4 components
with the per-sample argb8888 result."
So in several cases the lowering was updating the number of
components, so we need to update the writemask too.

We reserved space for chaining by subtracting 4 words from max_dw, but
then the new alignment code in radv_amdgpu_cs_finalize ended up running
all over that. That resulted in going over buffer size when chaining.
When lucky you'd get a crash, and when unlucky other stuff might happen.
This always adds the 4 words at the end, but initializes with NOP by
default. That way we still adhere to the alignment rules.
