It shows up as a special (magic?) attribute. We could try to be clever
and only include the extra record if gl_VertexID is actually read, but
honestly that's just extra complexity for no good reason. Might as well
just always include it; this won't be a real bottleneck, I don't think.

Just like varyings have special records for point coordinates (etc),
attributes have special records for vertex/instance ID. We can parse
these fairly easily, although they don't line up exactly with normal
attribute records.

Padded counts are numbers of the form:
n = (2k + 1) * 2^s
for k, s integers. Rather than explicitly store k and s separately and
then compute this formula on demand, it's much cleaner to store the
padded number itself, which is what you manipulate most of the time.
When you do need k,s it is easy to factor by noticing the bitwise
representation:
s = ctz(n)
k = n >> (s + 1)

We need to reshuffle to sync up the shadow coordinate temporary with the

The GPU presents the state of the hardware front_face in internal
register 0 (i0), the range of which is 0.0f..1.0f.
This patch assigns the fragment shader input to this internal register.
Moreover, based on the internal front_ccw state, the value of the i0
register is inverted accordingly using SET.EQ/SEQ.NE instruction before
being further processed in the shader. This mimics the operation of the
NIR compiler.

More vertex buffers are used than the hardware supports. In
principle, we only need to make sure that less vertex buffers are
