I'm adding this script, since it's been quite useful for me. The code is somewhat ad-hoc, but it does the job well enough. Possible future extensions: it would be nice to filter trivial predicates for which we don't care whether they're repeated across stages. That could be done by actually parsing some DIL or staying with the ad-hoc nature, we could also add an optional argument with an allow-list of predicate prefixes. Regardless, as-is it's quite useful to get an overview of the different stages in DIL and their overlap. The script also works on concatenated DIL from several queries (which is what you get when you dump DIL from compiling an entire suite).
