Great example of why "everything is a tree" sucks

You are clearly misreading what the C front end does then.  It doesn't have
any IL other than trees, and uses trees for everything from the start.

And, the problems with the FEs you've talked about aren't caused by using
trees, but by folding stuff too early.  It got somewhat better in the C FE,
but the C++ FE still folds things too early everywhere.
