The null program plus the one construct that links foreign.js.

Kept beside NULL_PROGRAM because the pair is the measurement: the difference between what these two ship is exactly what a DOM-owning foreign costs, and stating it as a diff is what stops the split from being a way to make the headline number smaller than the truth.
