Summary: Verify that each DBG_VALUE has a debug location. This is required by LiveDebugValues, and perhaps by other late passes. There's an exception for tests: lots of tests use a two-operand form of DBG_VALUE for convenience. There's no reason to prevent that. This is an extension of D80665, but there's no dependency.
