I've finished a run comparing this PR with tip of tree @ e887f8290df419ffd4e018b6f8afbaeb1912cf0e, and there's some really nice performance gains: 11% on 538.imagick_r and 10% on 508.namd_r! With -mcpu=spacemit-x60 -O3 -flto.

I'm re-running imagick and namd just to double check, but otherwise this is great!
