bfd1fc9cd6 vkd3d-shader/ir: Assume that Hull Shaders have a control point phase in vsir_program_normalise_io_registers(). 
The control point phase is always introduced, when missing, by the
earlier instruction_array_normalise_hull_shader_control_point_io()
pass.

eb71a1722a vkd3d-shader: Use an extended version of vkd3d_shader_immediate_constant in vkd3d_shader_parameter1. 
This is a proposed API change in 946, which won't make it into this release.

The intent is to allow slightly larger constants to be specified in the updated
vkd3d_shader_parameter1 structure. In particular, this is large enough to pass
4-dimensional integer or float vectors inline, which the proposed clip plane
implementation will use, as well as other Direct3D FFP parameters.

We could also simply add vkd3d_shader_immediate_constant1 as a separate union
member in vkd3d_shader_parameter1, but this API is a bit cleaner and simpler.

98def3214b vkd3d-shader: Introduce struct vkd3d_shader_parameter_info and struct vkd3d_shader_parameter1. 
As the newly added documentation describes, this reroll serves two purposes:

* to allow shader parameters to be used for any target type (which allows using
  parameters for things like Direct3D 8-9 alpha test),

* to allow the union in struct vkd3d_shader_parameter to contain types larger
  than 32 bits (by specifying them indirectly through a pointer).

8c15377ffc 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considered superseded and is therefore removed.

51f13391e6 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.

19aef21369 vkd3d-shader/ir: Handle PHI nodes when materializing SSA registers. 
PHI nodes cannot be used with TEMP registers, so they have to be
converted to MOV/MOVC nodes and moved before the BRANCH node.

e0d3e9c376 vkd3d-shader/ir: Materialize SSA registers to temporaries. 
For simplicity PHI nodes are not currently handled.

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.

378109051c vkd3d-shader/ir: Lower monolithic switches to selection ladders. 
PHI nodes must be fixed up after this pass, because the block references
might have become broken. For simplicitly this is not handled yet.

The goal for this pass is to make the CFG structurizer simpler, because
only conditional and unconditional branches must be supported.
Eventually this limitation might be lifted if there is advantage in
doing so.

4c30b23821 vkd3d-shader: Make the control point count the outer dimension of I/O arrays. 
The relative-addressed case in shader_register_normalise_arrayed_addressing()
leaves the control point id in idx[0], while for constant register
indices it is placed in idx[1]. The latter case could be fixed instead,
but placing the control point count in the outer dimension is more
logical.

418e8d8100 vkd3d-shader/ir: Expand index range write masks to cover all element masks. 
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.
