    OpenMP/C++: Use STRIP_REFERENCE_REF to fix declare variant with 
reference-returning functions
    
    As Jakub suggested, use STRIP_REFERENCE_REF instead of doing it manually
    as r15-4800-geb828a1e380e7b did.
    
    gcc/cp/ChangeLog:
    
            * decl.cc (omp_declare_variant_finalize_one): Use 
STRIP_REFERENCE_REF
            instead of doing it manually.
