; Other tests verify that we come back with reasonable structure for the debug
; info types, this test just needs to ensure they are there.
; The patch this is paired with fixes a bug where function debug info wasn't
; being emitted correctly even though other tests verified the MD would be
; emitted if it was referenced as module metadata.
