[PATCH] D89890: [Docs] Clarify that FunctionPasses can't add/remove declarations

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

Ideally they'd be module passes, like in https://reviews.llvm.org/D86178.
It does look like some existing legacy and NPM function passes break this rule. Maybe I should revert and ask more explicitly on llvm-dev. WDYT?
