ARMv6 optimized subtract functions Adds following ARMv6 optimized functions to encoder: - vp8_subtract_b_armv6 - vp8_subtract_mby_armv6 - vp8_subtract_mbuv_armv6 Gives 1-5% speed-up depending on input sequence and encoding parameters. Functions have one stall cycle inside the loop body on Cortex pipeline. Change-Id: I19cca5408b9861b96f378e818eefeb3855238639
