Record internal state based on register units. This is often more efficient as there are typically fewer register units to update compared to iterating over all the aliases of a register. Original patch by Matthias Braun, but I've been rebasing and fixing it for almost 2 years and fixed a few bugs causing intermediate failures to make this patch independent of the changes in https://reviews.llvm.org/D52010.
