[pypy-dev] New branch for performance experiments.

[Anders Chrigström]

I'm creating the branch 
ssh://codespeak.net/svn/pypy/branch/arre-experiments to use for 
experimenting with performance. The first of these will be trying to 
refactor the usage of the Arguments objects so that fewer objects get 
created when it is used. This is a part of the work to get creation of 
applevel user-defined objects go faster.
