[issue4111] Add DTrace probes

Look at these lines at the beginning of phelper.d:

#if defined(__i386)
#define        startframe PyEval_EvalFrameEx
#define        endframe PyEval_EvalCodeEx
#elif defined(__amd64)
#define        PyEval_EvalFrameEx PyEval_EvalFrameExReal
#define        startframe PyEval_EvalFrameExReal
#define        endframe PyEval_EvalCodeEx
#elif defined(__sparc)
#define        PyEval_EvalFrameEx PyEval_EvalFrameExReal
#define        startframe PyEval_EvalFrameEx
#define        endframe PyEval_EvalFrameExReal
#endif

You may need to adjust these if your compiler defines
something different from the __i386 or __amd64.
I guess an

#else
#error your architecture was not recognized
#endif

would be useful here.
