Erik Faye-Lund bff2986b3c virgl: work around bad assumptions in virglrenderer
Virglrenderer does the wrong thing when given an instance divisor;
it tries to use the element-index rather than the binding-index as
the argument to glVertexBindingDivisor(). This worked fine as long
as there was a 1:1 relationship between elements and bindings,
which was the case util 19a91841c3 "st/mesa: Use Array._DrawVAO in
st_atom_array.c.".

So let's detect instance divisors, and restore a 1:1 relationship in
that case. This will make old versions of virglrenderer behave
correctly. For newer versions, we can consider making a better
interface, where the instance divisor isn't specified per element,
but rather per binding. But let's save that for another day.
