[Python-Dev] patch: speed up name access by up to 80%

[Skip Montanaro]

    The only thing I'd change is that if PyDict_GetItem_Fast is a macro that
    only works for interned strings, I'd change its name to reflect its use:
    PyDict_GET_ITEM_INTERNED or something similar.

One other naming change is to prefix PyDict_GetItem_Fast2 with an
underscore, since the comments about its use make it clear that it's an
internal function.
