Comment (by gk):

 While digging into how the optimization is actually working and how Rust
 is using that I realized that we might be able to play with the
 optimization flags to narrow things further down if we don't find a better
 approach (`librustc_codegen_llvm/brack/write.rs` has the `optimize()`
 function which is a good start:
 {{{
     if config.opt_level.is_some() {
 }}}
 ). There are more options that might play a role here (see:
 `with_llvm_pmb()` as well).
