ARM: NEON optimization for bilinear scaled 'src_8888_0565'
Benchmark on ARM Cortex-A8 r2p2 @1GHz, 32-bit LPDDR @200MHz:
Microbenchmark (scaling 2000x2000 image with scale factor close to 1x):
before: op=1, src=20028888, dst=10020565, speed=6.56 MPix/s
after: op=1, src=20028888, dst=10020565, speed=61.65 MPix/s
