c691551249 Optimize tessellation code (min 20% better, up to 300% with some CD layers to tessellate). 
The main idea is to store (during tessellation) or recreate (during tessdata update) a tessfaceverts-to-loops mapping, and then update all tessdata
in one pass, instead of calling `BKE_mesh_loops_to_mface_corners` repeatedly for all tfaces!
