PR27938: Don't remove valid DebugLoc in Scalarizer

Authored by Ka-Ka on May 31 2016, 3:51 AM.



Added checks to make sure the Scalarizer::transferMetadata() don't
remove valid debug location's from instructions. This is important as
the verifier pass require that e.g. inlinable callsites have a valid
debug location.
