Optimize PyUnicode_RichCompare() for Py_EQ and Py_NE: always use memcmp()
--
I will benchmark the overhead of memcmp() on short strings. We may
check the first and last characters before calling memcmp() to limit
the overhead of calling a function.

I also read that GCC uses its builtin memcmp() which is slower than
the memcmp() of the GNU libc.
