PR 84519 Handle optional QUIET specifier for STOP and ERROR STOP

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.

Regtested on x86_64-pc-linux-gnu.
