Is there not like a "-O3" option to try aggressive code manipulation like that? Or is moving code around just not done at all because it's difficult to do correctly?

I think rematerialization covers most of the cases in which you would benefit from doing that (such as ax and xx), and rematting is standard in advanced compilers like GCC/LLVM.
