2a7b3f20ebb8007546b78496755a80fdf609fb66 first pass of using NEON
NEON has all sorts of handy instructions for us to play with:
- deinterlacing loads and interlacing stores
- vectorized bswap
- f16<->f32 conversion
These should be faster, and if nothing else cuts about 1.2KB of code.
f16 conversion is a separate bit (__ARM_FP & 2) that'll always be set on
ARMv8 but not necessarily on ARMv7. One day I may need to add an ARMv7
bot...
The _888 and _8888 stages might be able to benefit from NEON too, but
they're a little more awkward because there's no uint8x4_t in NEON, so
I've left them out of this CL. The _8888 stages might be hard to beat
as-is. Not much we can do for 1010102 AFAIK.
