There are many unrelated changes making this PR difficult to review.

I've set this as a draft for now, and I have split off two of the optimizations as separate PRs to make it easy to review: https://github.com/GlasgowEmbedded/glasgow/pull/652 https://github.com/GlasgowEmbedded/glasgow/pull/651

I will clean this PR up once those PRs are resolved.
