  • Allow MTRSX to work well with the vertex cache.
  • Optimize the vertex cache routines. It is now around 5x faster than before in games with decent hit ratios. In overall terms, we get a ~5-10% in draw-call-limited scenarios (e.g infamous)

This PR introduces use of robin-hood, a drop-in replacement for std::unordered_map that is much faster with large datasets.
