This fixed a whole set of bugs for us but it also seems to have caused a regression.

The details are in the upstream issue with a pure llvm IR reproducer. I could reproduce on ToT and reverting this PR made me unable to reproduce it.
The reproducer is a bit flaky and needs to be run several times.
