Do I understand right that with this patch, if the call is inlined late, then that message is dropped and replaced by a new "late inline.." message? If that's the case, isn't it the case that sometimes the `InlineTree::ok_to_inline()` has some useful information that's lost when late inlining happens?

Yeah I think you're right. It should not matter for the string/methodhandle/vector/boxing late inlines. But we can lose information for generic late inlines, for example a hot method that could not get inlined earlier due to lack of budget. I'll look into it.
