* headers.txt (gnu/gcj/jvmti/Breakpoint.h)[DIRECT_THREADED]:

        Add _Jv_RewriteBreakpointInsn friend declaration.
        * gnu/gcj/jvmti/natBreakpoint.cc (_Jv_RewriteBreakpointInsn)
        [DIRECT_THREADED]: New function.
        * gnu/gcj/jvmti/Breakpoint.h: Regenerate.
        * interpret-run.cc: Define new REWRITE_INSN macro.
        Changed all occurrences of insn rewriting to call REWRITE_INSN.
