Good point.
It *would* be really interesting to have some way to check our assumptions
(both ways - warn about over-large inlines and small-and-hot non-inlines).
I considered making sparse give some size estimate for inlines and warn
about ones that generate a lot of code, but I was never able to do it
sanely.
