[issue11549] Rewrite peephole to work on AST

[Nick Coghlan]

Eugene: I suggest raising the question on python-dev. The answer potentially affects the PEP 380 patch as well (which adds a new attribute to the "Yield" node).

Anatoly: If you just want to get a feel for the kind of AST various pieces of code produce, then the "ast.dump" function (along with using the ast.PyCF_ONLY_AST flag in compile) may be enough.

You may also want to take a look at the AST -> dot file conversion code in Dave Malcolm's patches on #10399.
