vkd3d-shader/ir: Emit multilevel jumps in the structured program.
...
The new structurizer therefore reaches feature parity with the
older simple one, except for a couple of points:
* the old structurizer accepts any CFG, without requiring reducibility;
however, the DXIL specification requires the CFG to be reducible
anyway, so we're not really losing anything;
* the new structurizer additionally requires that no block has two
incoming back arrows; AFAIK this is condition that can happen,
but in practice it seems to be rare; also, it's not hard to add
support for it, as soon as it is decided it is useful.
On the other hand, the new structurizer makes use of the merging
information that are reconstructed from the CFG, which is important
for downstream optimization and fundamental for correctly emitting
tangled instructions.
Taking these considerations into account, the old structurizer is
considered superseded and is therefore removed.

vkd3d-shader/ir: Introduce a simple control flow graph structurizer.
...
The structurizer is implemented along the lines of what is usually called
the "structured program theorem": the control flow is completely
virtualized by mean of an additional TEMP register which stores the
block index which is currently running. The whole program is then
converted to a huge switch construction enclosed in a loop, executing
at each iteration the appropriate block and updating the register
depending on block jump instruction.
The algorithm's generality is also its major weakness: it accepts any
input program, even if its CFG is not reducible, but the output
program lacks any useful convergence information. It satisfies the
letter of the SPIR-V requirements, but it is expected that it will
be very inefficient to run on a GPU (unless a downstream compiler is
able to devirtualize the control flow and do a proper convergence
analysis pass). The algorithm is however very simple, and good enough
to at least pass tests, enabling further development. A better
alternative is expected to be upstreamed incrementally.
Side note: the structured program theorem is often called the
Böhm-Jacopini theorem; Böhm and Jacopini did indeed prove a variation
of it, but their algorithm is different from what is commontly attributed
to them and implemented here, so I opted for not using their name.

The goal for this pass is to make the CFG structurizer simpler, because
it doesn't have to care about the more rigid rules SSA registers have
to satisfy than TEMP registers.
It is likely that the generated code will be harder for downstream
compilers to optimize and execute efficiently, so once a complete
structurizer is in place this pass should be removed, or at least
greatly reduced in scope.

The relative-addressed case in shader_register_normalise_arrayed_addressing()

logical.

For example, this occurred in a shader:
reg_idx write_mask
0 xyz
1 xyzw
2 xyzw
3 xyz
The dcl_indexrange instruction covered only xyz, so once merged, searching for
xyzw failed.
It is impossible to declare an input array where elements have different
component counts, but the optimiser can create this case. One way for
this to occur is to dynamically index input values via a local array
containing copies of the input values. The optimiser converts this to
dynamically indexed inputs.

Regression in signature normalisation, however the old code was not
correct either because it would apply the interpolation mode to all
components. Found in an Assassin's Creed: Valhalla shader.

The previous computation was incorrect because the count was taken

Hull shaders have a different temps count for each phase, and the
parser only reports the count for the patch constant phase.
In order to properly check for temps count on hull shaders, we first
need to decode its phases.

vkd3d-shader: Rename vkd3d_shader_next_stage_info to vkd3d_shader_varying_map_info.
...
It was originally intended that this structure could hold other information
about the next stage which compilation might depend on. For example, compilation
to GLSL needs to know the type of the next shader in some circumstances.
That was never actualized, and since the API is fixed at this point for 1.9, it
makes the most sense to rename the structure to match its actual scope.
The documentation was written and arranged to imply that the structure would
hold other information about the next shader than the varying map; this is
changed accordingly as well.
