Oliver Stannard 1c6e591457 [ARM] Improve error messages for .arch_extension directive
- More informative message when extension name is not an identifier token.
- Stop parsing directive if extension is unknown (avoid duplicate error
  messages).
- Report unsupported extensions with a source location, rather than
  report_fatal_error.
