Cut performance cost in QSGContext::prepareMaterial()
The hash-lookup in this function is costing us a lot, and
since we're looking up the same materials again and again,
and the material has a place holder for it, we can store it
directly in the material at no extra cost. This was a 10%
gain in this particular benchmark.
