The new message is: "Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace." 1. In crash logs we used to print a message which points to the llvm bug tracking page. Now it points to the swift.org bug tracking guidelines. 2. Use the same message in all compiler diagnostics which ask the user to file a bug report. rdar://problem/70488534
