Add entry and benchmark for a new Fortran-specific checker. My results:

$ gfortran --version                
GNU Fortran (Debian 12.2.0-14) 12.2.0

PWR068 Fortran Example        3463 us         3463 us          203
PWR068 Fortran Improved       3466 us         3465 us          202

As can be seen, the recommended code modernization does not incur any performance downgrade.
