Though this is mostly meant to be "NFC" (with very large quotes), I can imagine us doing something like forcing the parsing of a specific type (`type lookup <something>` ?), and then checking that the module ast (`image dump ast`) does _not_ contain specific types -- as that's basically what we're trying to achieve.

In terms of testing, since this only delays definition DIE searching not type completion, we need to construct a test so that lldb finds the declaration DIE first without trigger a type completion on it and somehow test the incomplete type. The first part is tricky. I'm not sure how to achieve it.
