* To avoid the build time overhead of checking for relocated modules, only check it once per build session. * Enable relocated module checks in the dependency scanner. * Add remarks to know when this is happening with `-Rmodule-validation` This check is necessary to be able to handle new libraries appearing in earlier search paths. This is a valid scenario when dependency info changes between incremental builds of the same scheme, thus new build sessions. It is still malformed to expect new versions of libraries to be added within the same build session. resolves: rdar://169174750
