The expected behavior for implicitly built modules is to validate input files and to rebuild a module if there are any input file changes. But if for some reason a module hasn't been rebuilt, it is useful to know if the validation has been done and what kind of validation. The goal is to make investigations for fixes likef2a3079a1bandada79f4c26easier. rdar://159857416 --------- Co-authored-by: Cyndy Ishida <cyndyishida@gmail.com>
