A 2% speed improvement with gcc on low-endian machines. My guess is that this

new pattern for NEXTARG() is detected and optimized as a single (*short)
loading.

Speedup for-loops by inlining PyIter_Next(). Saves duplicate tests
...
and a function call resulting in a 15% reduction of total loop overhead
(as measured by timeit.Timer('pass')).

Refactor and optimize code for UNPACK_SEQUENCE.
...
* Defer error handling for wrong number of arguments to the
unpack_iterable() function. Cuts the code size almost in half.
* Replace function calls to PyList_Size() and PyTuple_Size() with
their smaller and faster macro counterparts.
* Move the constant structure references outside of the inner loops.

SF patch #884022 : dynamic execution profiling vs opcode prediction
...
(Contributed by Andrew I MacIntyre.)
disables opcode prediction when dynamic execution
profiling is in effect, so the profiling counters at
the top of the main interpreter loop in eval_frame()
are updated for each opcode.

Simplified version of Neal Norwitz's patch which adds gotos for

Formerly, the length was only fetched from sequence objects.
Now, any object that reports its length can benefit from pre-sizing.
