    c++: Avoid duplicate trivial_abi cleanup in cdtor clones [PR125066]
    
    Constructor and destructor clones already have a genericized copy of the
    original body, including parameter cleanups.  Do not add another front-end
    CLEANUP_STMT while processing a clone.
    
    gcc/cp/ChangeLog:
    
            PR c++/125066
            * decl.cc (store_parm_decls): Do not register trivial_abi parameter
            cleanups for cloned functions.
    
    gcc/testsuite/ChangeLog:
    
            PR c++/125066
            * g++.dg/cpp0x/attr-trivial_abi10.C: New test.
