This prevents a call to bytestream_get_be16() using a movzwl both before
and after the ror instruction, which is obviously inefficient. Arm uses
the same trick also.
Sintel decoding goes from (avg+SD) 9.856 +/- 0.003 to 9.797 +/- 0.003 sec.
We should replace most inlined uses of asm with compiler intrinsics.
What if we don't use gcc, though?
builtins vs inline asm... Not sure which is decently supported by
non-gcc compilers.
