Log Message:

Backport Jeremy's checkin 2.244:

Add a second special case to the inline function call code in eval_code2().

If we have a PyCFunction (builtin) and it is METH_VARARGS only, load
the args and dispatch to call_cfunction() directly.  This provides a
small speedup for perhaps the most common function calls -- builtins.
