Heh, yeah.  flatten with LTO will indeed have the possibility to inline very
many functions ;)  Note that all limits we expose on inlining (large function,
large unit, etc.) are not applied here.

Not sure if limiting flatten to early inlining would be a good idea (you'd
never get cross-module inlining on flatten that way, similar to always_inline).

Maybe we should impose a really-large-function limit ... (and flatten in
function size order).
