It's more relevant to look at just code size. BUG_ON() has more of an
impact on data sizes, because it does something like 10-12 bytes of
exception data for each bug-on. But that exception data is out-of-line and
not interesting.
If the code size blows up a lot, that's worse than if the data size
expands a bit.
