SSE2 version of blit_lcd16, courtesy of Jin Yang.
Yields 25-30% speedup on Windows (32b), 4-7% on Linux (64b, less register
pressure), not invoked on Mac (lcd text is 32b instead of 16b).
Followup: GDI system settings on Windows can suppress LCD text for small
fonts, interfering with our benchmarks.
