f1b8b6ae34 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.

8bf7b79cf9 Refactor swizzle names and types.
- Plant a flag to say "pretend all the inputs are RGBA".
    This is how libpng thinks.
    This is the opposite of what the implementation had been doing,
    so I've rearranged everything to reflect the new orientation.

  - Rewrite the names to be less mysterious looking.  No more Xs.

  - Make the src type uniformly const void*, to allow for 888 (RGB) srcs.

This should be performance and pixel neutral.  (Please revert if it's not.)
