    OpenMP/Fortran: Group handling of 'if' clause without and with modifier
    
    The 'if' clause with modifier was introduced in
    commit b4c3a85be96585374bf95c981ba2f602667cf5b7 (Subversion r242037)
    "Partial OpenMP 4.5 fortran support", but -- in some instances -- didn't place
    it next to the existing handling of 'if' clause without modifier.  Unify that;
    no change in behavior.
    
            gcc/fortran/
            * dump-parse-tree.cc (show_omp_clauses): Group handling of 'if'
            clause without and with modifier.
            * frontend-passes.cc (gfc_code_walker): Likewise.
            * gfortran.h (gfc_omp_clauses): Likewise.
            * openmp.cc (gfc_free_omp_clauses): Likewise.
