optimizations for D16 using SSE2

skia_bench -config 565 -match bitmap_8888_scale_filter -forceFilter 1 -repeat
30

The result I got on Android platform was below:

w/o this optimization routine: 
D/skia    ( 1868): running bench [640 480]     bitmap_8888_scale_filter
D/skia    ( 1868):    565: cmsecs = 286.50

w/ with optimization:
D/skia    ( 1463): running bench [640 480]     bitmap_8888_scale_filter
D/skia    ( 1463):    565: cmsecs = 186.80

The net gain is 34.80%.
