GrTessellator: fix crash on merging a dead edge.
When merging coincident vertices, sometimes merging an edge will cause
the next edge in the list to die. But since merge_vertices() retrieves
the next edge before merging the current one, we then try to merge its
lifeless corpse, bringing it back as a zombie. The fix is to leave
dead edges, dead.
This was revealed by ec79c39a770205910f0abd762de7e19a96c986ca, but was
likely a real bug that was being mishandled before that.
