Comment (by dfeuer):

 More importantly, the note is nonsense. Things not marked `INLINE` or
 (more strongly) `INLINE CONLIKE` sometimes won't be inlined even though
 they can be, once the code around them gets complicated enough. An
 operation like an unsafe shift, mask, etc., that's literally cheaper than
 a function call should *always* be inlined, unless I'm extremely confused.
