Fortran 2018 adds a new QUIET specifier for the STOP and ERROR STOP statements, in order to suppress the printing of signaling FP exceptions and the stop code. This patch adds the necessary library changes, but for now the new specifier is not parsed and the frontend unconditionally adds a false value for the new argument.
