Optimized Tessellation Comes To Mesa

Bas Nieuwenhuizen has published a set of patches which should be able to deliver dramatically better tessellation performance with Mesa on RadeonSI cards.

This patchset implements offchip tessellation after which we can finally process more than one patch per wave without decreasing tessmark scores.

For tessmark this improves performance by ~20% for the x32 case and ~80% for the x64 case. x8 and x16 have roughly the same performance as before. Unigine heaven gets 43 fps compared to 28 before (roughly +50%). Amdgpu-pro gets 44 fps for heaven. For Shadow of Mordor the performance changes from 28 fps to 40 fps (roughly +40%).

Note: These values have been archived with a Tonga GPU.
