Do I understand it correctly that Lilypond has lots of snippets that are
executed exactly once? In that case it could be expected that the
overhead of optimization dominates — maybe even the overhead of
increased code-size from inlining?

Also the new baseline compiler is already pretty good:

Maybe this?
