respond to review feedback: mainly eliminate as many conversions as possible...
- ... when creating diagnostics in rustc_metadata - use the error_code! macro - pass macro output to diag.code() - use fluent from within manual implementation of SessionDiagnostic - emit the untested errors in case they occur in the wild - stop panicking in the probably-not-dead code, add fixme to write test
