In an ideal world, that is what we would like to have.  But currently,
things are a bit intertwined -- and historically, it has been worse :-).
In the current state, the gimplifiers run even if -fsyntax-only.
Worse, they run even when we know the translation unit contains an error.

However, you might get a starting point from the codes that call hooks for
tree dumping.
