ARM: NEON optimization for bilinear scaled 'src_8888_8888'

Initial NEON optimization for bilinear scaling. Can be probably
improved more.

Benchmark on ARM Cortex-A8:
 Microbenchmark (scaling 2000x2000 image with scale factor close to 1x):
  before: op=1, src=20028888, dst=20028888, speed=6.70 MPix/s
  after:  op=1, src=20028888, dst=20028888, speed=44.27 MPix/s
