Mostly LGTM, but there are some minor comments. Most of them are not blockers for merging this, but for a couple of ones which are better to be resolved before merging the PR:
- Is there definitely smth MachO-specific or the corresponding assertion could be deleted? I've deleted it locally and tried to build against aarch64-elf triple, and it looks like that everything is OK.
- Comments related to code model
