This is a bit late on this, but we're currently trying to upgrade LLVM in Rust <https://github.com/rust-lang/rust/pull/51966> and we've run into a performance regression bisected to this change <https://bugs.llvm.org/show_bug.cgi?id=38088>, if those here familiar with this commit could help investigate that it'd be much appreciated!
