I am a bit surprised it looks like to be a bit higher than @nikic last measurements as I don't think anything functionally has changed (https://llvm-compile-time-tracker.com/compare.php?from=6f45fe9851c673883b3a258351ee4997aa2c028c&to=439d1c9613828db24ad03eb415baad2e76b8913c&stat=instructions).

We made it a LPM and it is preserving MSSA since Nikita's measurements, but again, was not expecting this to change things. Will do some more experiments.
