This I'm unsure of.  It's comparable to defining a C signature and calling it,
it works fine, it just means that someone over editing the object won't know
about it until runtime crashes (if they're lucky).  Rachel may have a stronger
opinion, but I have a weak opinion that this should be in the header, something
like:

@interface OmniboxPopupCellData (TestingAPI)

I'm fine with that crash, since it crashes _tests_ :)

But as-is, this is indeed not what I'm looking for - I'd like both test
interface *and* implementation to live in test files. The reason being that we
pay a memory cost if we just bundle testing APIs into the executable. Yes, it's
small, but it adds up.

Oh, yes, that's true.  If the implementation is only there for tests to mess
around with things, then by all means pull it into the test code.
