Lowering PS inputs can eliminate some of them, which messes up
persp/linear barycentric coord usage info.

We need to tell PA to accept edge flags generated by the input assembler,
because decomposed primitives shouldn't draw inner edges.

With NGG, the VGT_GS_OUT_PRIM_TYPE can change without a shader change.
The VS_STATE is required for both streamout and culling from a vertex
shader without pre-compiling outprim-specific variants.
We could consider compiling specialized variants in the future. We
could also consider compiling the NGG logic as an epilog.

For pipelines without API GS. We will later expand this to cover NGG
geometry shaders as well.
Note that the vtx offset passed into the GS part is just the
vertex index multiplied by VGT_ESGS_RING_ITEMSIZE.

Also add the shader main part NGG variant, so that in principle
we can switch between legacy in NGG modes.

We always use NGG by default, except when tessellation is enabled with

We'll have to extend this at some point, and using a bitfield union in
this way makes it easier to get the right index without excessive
branching.

This will make it easier to use LDS for other purposes in geometry
shaders in the future.
The lifetime of the esgs_ring variable is as follows:
- declared as [0 x i32] while compiling shader parts or monolithic shaders
- just before uploading, gfx9_get_gs_info computes (among other things)
the final ESGS ring size (this depends on both the ES and the GS shader)
- during upload, the "esgs_ring" symbol is given to ac_rtld as a shared
LDS symbol, which will lead to correctly laying out the LDS including
other LDS objects that may be defined in the future
- si_shader_gs uses shader->config.lds_size as the LDS size
This change depends on the LLVM changes for emitting LDS symbols into
the ELF file.

Upcoming changes to LLVM will emit LDS objects as symbols in the ELF
symbol table, with relocations that will be resolved with this change.
Callers will also be able to define LDS symbols that are shared between
shader parts. This will be used by radeonsi for the ESGS ring in gfx9+
merged shaders.
