fa1a6347e9 Weaken testing for controlfow branch 
We have more equivalent programs now

rocky
760532b218 Add COME_FROM_LOOP 
Note: we have regressed in --verify and some tests,
but I believe that's because we are producing more equivalant
(if uglier) programs. That's a separate problem though.

c7788e4545 disassemble -> ingest where appropriate 
As part of tokenization for (de)parsing, we need to do something like a
disassembly, but is is really a little different.

Disassembly, strictly speaking, is done by the xdis module now.
What "ingestion" does is massage the instruction tokens to a form that is
more amenable for parsing.

In sum, ingestion is different than disassembly, although disassembly is
generally the first part of ingestion.

47a56d3387 Python 2.3--2.6 bug in parsing try-middle 
Note: it looks like COME_FROMs need to be classified better
with respect to whether they are from an except or not
we are getting if/else vs except nesting errors.

b6fd9088b8 Python 2.3..2.6 "return" bug 
In Python 2.6 and possibly down to 2.3 we need to issue "return" not
"return None" inside a generator. So check for that "return None"
inside n_return and issue "return" for that.

If 2.6 or before POP_BLOCK after a JUMP_IF_FALSE does not
constitute a new statement. The POP_BLOCK is really part
of the JUMP_IF_FALSE. In Python 2.7+ it's a single op.
