[pypy-dev] Small dicts

[Armin Rigo]

Hi all,

"withsmalldicts" is not enabled by default, I suppose because we
measured that it didn't help.  However I've found a bug which I think
means that even when the option is enabled, they won't be used in most
common cases.  The bug is that the option is checked in
EmptyDictImplementation.setitem() but not in
EmptyDictImplementation.setitem_str(): the latter always creates a
non-small StrDictImplementation.

Anyone feels like fixing and re-measuring this?
