    arm: get_cabac inline asm · 634d9d8b

    Based on the aarch64 asm. CPU cycle counts on cortex-a9 compared to
    gcc 4.8.2:
    before: 475 decicycles in get_cabac_noinline, 67106035 runs, 2829 skips
    after:  393 decicycles in get_cabac_noinline, 67106474 runs, 2390 skips
    
    Overall speedup is above 2%. Code generated by clang 3.4 is slower on
    the same hardware and the relative change is a little larger.
