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.

f5eeed6759 2.6- bug: while..and: stmt - on one line 
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.
