First, few comments about the code.

1) The condition "a == b" is enough. No need to test "PyDict_CheckExact(a)" and like.

2) This fast path can be used only for Py_EQ and Py_NE. For other operations it can change the behavior.

This is common approach of implementing operator== on C++. Unless comparing objects is trivial the implementation of operator== almost always starts with comparing pointers. In Python the overhead of calling methods and comparing objects is larger than in C++ and I expect that the relative overhead of one additional pointer comparison is smaller.
