d43912b188 panvk: Handle input varyings without previous writes
Some input varyings might not be written by any of the active stages
preceding the stage reading the varying (e.g. gl_Layer should be set
to 0 when not written by vertex/geometry shaders). In this case, we can
insert a dummy varying attribute returning zero. This is actually what
the code intended to do, but 2 things were missing:

1. formats[NONE] is not mapping to the CONSTANT0 format
2. the offset and strides should always be set to 0 when using a
   CONSTANT0 attribute

All of this is needed to have the input attachments working. Indeed, we
use the nir_lower_input_attachments() pass which lowers input attachment
loads to texel fetches, and the txf operation is passed the layer_id
in its 3rd coordinate.

7371efdb3a i915g: Use the non-vbuf code path by default to fix index overflows.
We were assertion failing on some large draws due to indices >16bits,
despite asking draw to limit the max indices.  I haven't managed to track
it down, so flip us back to the older, non-index drawing path that doesn't
hit this bug until it can get fixed.  Leave an I915_DEBUG=vbuf flag around
so we can look into this later.

This is a pretty big performance hit for vertex shaders.  Using glmark2 -b
build:use-vbo=true:

i915g-vbuf:     211 fps
i915g-nonvbuf:  185 fps
i915c:          41 fps

Given how massively better i915g still is than i915c (llvmpipe VS instead
of the classic swrast interpreter), I think it's still worth it to get
i915g correct before we fix this perf regression.
