core/exception: beautify exception handler, add MCE-involved registers
Print DSISR and DAR, to help with deciphering machine check exceptions,
and improve the output a bit, decode NIP symbol, improve alignment, etc.
Also print a specific header for machine check, because we do expect to
see these if there is a hardware failure.
