This fprintf() was added in commit cce3bea2a7 ("i965/disasm: Align send
instruction meta-information with dst.")) to align the human-readable
send message info (e.g. "render MsgDesc: RT write ...") with the
destination register on the previous line.
Two months later we disabled printing the instruction offset in commit
662f1ccc24 ("i965: Disable hex offset printing in disassembly."),
thereby unaligning the human-readable send message info for the next 11
years.
