940725a7d9 broadcom/compiler: implement gl_PrimitiveID in FS without a GS 
OpenGL ES 3.1 specifies that a geometry shader can write to gl_PrimitiveID,
which can then be read by a fragment shader.

OpenGL ES 3.2 additionally adds the capacity for the fragment shader
to read gl_PrimitiveID even if there is no geometry shader. This
commit adds support for this feature, which is also implicitly
expected by the geometry shader feature in Vulkan 1.0.

82fadbd3ab v3d: better scissor tracking 
If all drawing is scissored but we have multiple discontinuous
scissor rects, we end up flushing all the tiles in the rect that
covers all scissor rects, which can be a waste, particularly for
large render targets. The obvious case for this are updates to a
mega texture or atlas for example.

This change checks if all rendering happenings against scissor
rects, in which case it keeps track of the rects and uses this to
discard tiles that are not included in any of them.

This optimization needs to be disabled if we have any
non-scissored rendering, including non-scissored clears.

0bb543bb60 ac/nir: Reuse uniforms from top part of culling shaders. 
Uniforms have the same value in all invocations, therefore they

UBO loads and such.

We exclude uniform floats, because those would harm the VGPR
usage of the shaders too much.

f30e4351de radv: Support NGG culling with new perftest environment variable. 
Currently we don't enable it on any chip by default, but
we plan to enable it soon on GFX10.3 when we are comfortable
with its performance.

RADV_PERFTEST=nggc environment variable enables it on GFX10+ GPUs.

182d9b1e60 aco: Implement NGG culling related intrinsics. 
These are very straightforward as they just copy data from
the newly added shader arguments.

9a95f5487f radv: New shader args for NGG culling settings and viewport. 
Add new shader arguments in RADV for:
- NGG culling settings
- Viewport transform

These will be used by NGG culling shaders.

Additionally, some tweaks are made to some config registers
in order to make culling shaders more efficient.

ed163a44b6 radv: Expose radv_get_viewport_xform in radv_private.h 
We need to emit viewport transform information for culling shaders.
This is used for small primitive culling.
