Might as well inline these premultiplies. We're paying quite a bit of function-call overhead per pixel. On one test image we spend 3.5% of our total time in swizzle_rgba_to_n32_premul() and 8.8% of our total time in SkPreMultiplyARGB(). That turns into just 8.8% of our total time in swizzle_rgba_to_n32_premul() after inlining. That's about a 30% speedup. This will make SIMD procs look worse, so it's nice to land this first.
