The remaining change for neon-strided-load-extract is to allow fwprop.c to propagate:
(set (reg X) (subreg (reg Y) N))
even if no further simplifications are possible. I posted the original patch for comments here:

and fixed the problem that H.J. spotted. I wasn't entirely happy with the benchmark results though, so it never became an RFA.
When you say you weren't happy with the benchmark results - would you remember if it didn't show any significant improvements or were there significant regressions ?
There were some nice improvements but a couple of regressions. I don't remember the regressions being very big, but they were outside the noise, so I wanted to explain them first.
