[issue2963] Method cache is broken in Py3

[Stefan Behnel]

New submission from Stefan Behnel <scoder at users.sourceforge.net>:

The method cache is deactivated in current Py3. As Lisandro Dalcín
noticed, the following code in typeobject.c always returns false for a
Py3 identifier:

#define MCACHE_CACHEABLE_NAME(name)                                     \
		PyString_CheckExact(name) &&                            \
		PyString_GET_SIZE(name) <= MCACHE_MAX_ATTR_SIZE
