Filing this to keep track of llvm/llvm-project@6b539f5 breaking tests/codegen/lto-removes-invokes.rs and tests/codegen/sanitizer/sanitizer-recover.rs#MSAN-RECOVER-LTO, both with the message error: failed to get bitcode from object file for LTO (Bitcode section not found in object file).

In https://reviews.llvm.org/D152973#4520240 it sounds like we should already have an idea of what to do here, but I also have the vague notion it might not be a quick fix, so I'm opening a bug that I can refer the handful of Rust-at-HEAD/LLVM-at-HEAD users to until we get this resolved.
