Huh, interestingly, that Merriam Webster link is the only one I can find that acknowledges `leafs` as a plural for the general case.  The only other case I could find was wiktionary: https://en.wiktionary.org/wiki/leaf

Which shows that `leafs` is valid in 2 cases: when talking about multi-section doors, or when used as a pejorative for a Canadian.  So I don't really know anything anymore.

That said, while LLVM's policy is only 'english' and doesn't specify American, Canadian, or British English, by practice we use American English spellings for things.
