Description Chris Dumez 2018-07-18 15:24:07 PDT 
Better deal with unexpected descriptor types in IPC::Connection's createMessageDecoder() so that decoding actually fails instead of adding default-constructed IPC::Attachment objects to the Decoder.
We have cases where decoding succeeds but the mach_port passed via IPC is null (rdar://problem/41995022) and this could be the cause.
