Paul Wilkins 35bb74a6bd Rationalize vp8_rd_pick_intra16x16mby_mode()
Use the function macro_block_yrd() to calculate error and distortion
in keeping with what is done for inter frames.

The old code was using a variance metric for once case and an
SSE function for measuring distortion in the other case.

The function vp8_encode_intra16x16mbyrd() is no longer used.
