Use NEON optimizations for RGB -> RGB(FF) or BGR(FF) in SkSwizzler
Swizzle Bench Runtime Nexus 6P
xxx_xxxa 0.32x
xxx_swaprb_xxxa 0.31x
Swizzle Bench Runtime Nexus 9
xxx_xxxa 1.11x
xxx_swaprb_xxxa 1.14x
(This is a slow down.)
Swizzle Bench Runtime Nexus 5
xxx_xxxa 0.12x
xxx_swaprb 0.12x
RGB PNG Decode Runtime
Nexus 6P 0.94x
Nexus 9 0.98x
I don't know how to explain the fact that the Swizzle Bench was
slower on Nexus 9, but the decode times got faster.
