Actually, it doesn't need to be called very late. And, I don't think this is applicable to AArch64 only.
I've been experimenting with a few potential improvements in LLVM that could bring benefits to AArch64 Aggressive optimization mode, so this patch just follows that direction (that's why it was marked as WIP).
