So a lot of alterations had to be done to make this not worse and so far, it's not really better, either. I had to force inlining for the adler routine, I had to remove the x4 load instruction otherwise pipelining stalled, and I had to use restrict pointers with a copy idiom for GCC to inline a copy routine for the tail. Still, we see a small benefit in benchmarks, particularly when done with size of our window or larger. There's also an added benefit that this will fix #1824.
