      Description

        From: martin.doerr@sap.com

        we had run -Xcomp tests on aarch64 and got SIGSEGV in StubRoutines::generic_arraycopy (debug build).

        generate_generic_copy:
        rscratch2_dst_klass = rscratch2 = r9

        It uses
        MacroAssembler::check_klass_subtype_slow_path
        which overwrites rscratch2 in debug build.
