Yes, I think it will be possible to divide the patch into several separate ones. However, they will depend on the patch with changes to intruction selection patterns (commit 9e5fbe0), which should be processed first. This patch affects changes in tests related to FPSCR  (e.g. Thumb2/mve-fmas.ll). Therefore, at first it would be better to decide on the position regarding this issue, after which it will be possible to split the patch.

As for how to organize the patches after separation: should each individual patch have a separate PR?
