The face culling algorithm should have been disabled for
conservative overestimation because it already
(mistakenly) removed some close-to-zero area triangles.
Now that the driver disables it in that case,
let's always remove zero-area triangles.
This only costs +2 SALU instructions.

Even when small primitive culling is disabled, the face culling algorithm
in ac_nir_cull can delete tiny triangles when their area is almost zero.

When all shader stages have already been imported it's possible to
skip radv_graphics_pipeline_compile() entirely. This makes GPL
fast-linking VERY fast.

Only the blend state was relying on the graphics pipeline key. This
will allow us to skip generating it when there is no compilation at
all (for fast-linking with GPL).

Otherwise, a noop FS will be always compiled during linking if not
provided by the application and that is too slow for fast-linking.
This should be improved to use a global noop FS but it's really tricky
because NIR linking doesn't do anything when the next stage is unknown,
and hence doesn't remove unused varyings.

People who use RADV on eGPU have reported poor performance by default.
They also noted that the "nosam" option helps.
This commit disables placing CS objects in VRAM when the bandwidth is
below that of PCIe 3.0 x8. Note that eGPUs are typically PCIe 3.0 x4.

This is so that we can tell whether the current kernel
has the PCIe bandwidth info available or not.

To fix a hypothetical issue:
v0 = start_linear_vgpr
if (...) {
} else {
use_linear_vgpr(v0)
}
v0 = phi
We need a p_end_linear_vgpr to ensure that the phi does not use the same
VGPR as the linear VGPR.
This is also much simpler.
