Similarly to the HW VS stage, the HW NGG GS stage also
benefits from executing these exports as early as possible.

When NGG is used, vertex and tess eval shaders are executed on the
hardware NGG geometry stage. There is a series of steps they
must perform:
* Request GS space using GS_ALLOC_REQ
* Export the primitive
* Finally, export the normal VS outputs
In this commit, two modes are implemented:
* "late" which matches what the RADV LLVM backend currently does
* "early" which is an optimized version as seen in radeonsi
Vulkan doesn't allow the shader to write the edge flags, so we can
currently always use the "early" mode.
Exporting the primitive ID is also supported by having the GS threads
write that into LDS and reading them from LDS in the ES threads.

ngg_vertex_gs and ngg_tess_eval_gs work very similarly to
vertex_vs and tess_eval_vs, but they run on the HW NGG GS stage.

The exports in NGG VS and TES work just like VS exports,
so the assembler needs to fix these too in the same manner.

They behave like merged ESGS shaders, so the exec mask needs
to be manually initialized for these NGG shaders too.

This is needed to distinguish between NGG and legacy.
Otherwise, vertex_geometry_gs and ngg_vertex_geometry_gs
have the same value, which we want to avoid.
Also, there is no such thing as ngg_vertex_tess_control_hs.

We want to execute instructions after s_setprio in the given
priority, so we must prevent the scheduler from scheduling beyond
s_setprio, otherwise some instructions could be executed in a
different priority.
Rename hazard_fail_memtime to hazard_fail_unreorderable and include
s_setprio in the list of unreorderable opcodes.

but we are going to need to use it with some NGG code as well.

This isn't perfect (for example, changes might not be too meaningful when
comparing shaders with different control flow) but it should be useful for
evaluating scheduler changes.
