[Python-Dev] Suggest reverting today's checkin (recursive constant folding in the peephole optimizer)

[Eugene Toder]

To give this a positive spin, here's a patch that implements constant
folding on AST (it does few other optimizations on compiler data
structures, so it replaces "peephole over bytecode" completely).

It passes make test, but of course more testing is needed. Comments are welcome.
