fa7d8f955a WIP Python-2.6 but don't remove opcodes
The scheme for turning 2.6 bytecode into 2.7 psuedo bytecode
I think is a lose.

I won't work for fragment handling.

Instead, change the grammar and syntax rules

This also has the benefits:

* We see how code generation changed over releases
  by looking at grammar and semantic rules rather
  than arbitrary code
* We can better assocate with what's running
  (in a sense this is a restatement of broken fragment
   handling)
* With the right structure in place we are in a better position to
  handle 2.5, 2.4, etc. That is, after a while, the incremental changes
  to get say from python 2.3 bytecode to python 2.7 are great.

982a6010a1 WIP 2.6 redo bytecode handling
Don't try to convert 2.6 bytecode to 2.7 psuedo bytecode.
Instead adjust grammar and semantic actions.

Down the line we should to segregate version changes in
semantic code better.
