Looking at the LLVM API docs that Xi referred to, the LLVM preference
is actually pretty weak.
So I'd almost say continue with the current IR, and just do the
pointer arithmetic by hand. If LLVM doesn't treat GEP *that*
specially, doing a separate pointer arithmetic level is quite possibly
going to just cause problems: simplification of combinations of GEP
and arithmetic is potentially quite annoying and has problems that
simplification of perfectly regular addition does not.
