The debug-use flag must be set exactly for uses on DBG_VALUEs. This is so obvious that it can be trivially inferred while parsing. This will reduce noise when printing while omitting an information that has little value to the user. The parser will keep recognizing the flag for compatibility with old `.mir` files.
