This revision is now accepted and ready to land.
LGTM basically. I still feel we need a FIXME there. But I don't want to block
this for this reason especially we need to land this before the branch.

It looks hacky to me since we shouldn't care if it is deleted or defaulted here
and it should be enough to check `FD->isInlied()`. And I don't see similar
usage of `BodyKind ` in this function.

+ !FD->isInvalidDecl() && BodyKind == FnBodyKind::Other &&
+ !FD->isInlined()) {

Oh, I found it now. It may be better to have an assertion
`assert(FD->isThisDeclarationADefinition())`.
