General clean up of error handling in llvm-objdump to remove its use of report_fatal_error().
No real functional change with this commit. The problem with report_fatal_error() is it does not include the tool name and the file name the for which the error message was generated. Uses of report_fatal_error() were change to report_error() or error() to get a better error and to make the code smaller and cleaner. Also changed things like error(errorToErrorCode(SOrErr.takeError())) to use report_error() with a file name and the llvm::Error (as well as the ArchitectureName if available) so the error message is printed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@287163 91177308-0d34-0410-b5e6-96231b3b80d8
