1fc8ac4700 Interval order COME_FROMs in Python3 
This bug had possibly caused lots of grammar pollution which may need
addressing.

We want to process COME_FROMs to the same offset to be in *descending*
order so we have the larger range or biggest instruction interval
last. (I think they are sorted in increasing order, but for safety
we sort them). That way, specific COME_FROM tags will match up
properly. For example, a "loop" with an "if" nested in it should have
the "loop" tag last so the grammar rule matches that properly

Adjust Python 3 grammar for more COME_FROM -> COME_FROM_LOOP. And
remove optional COME_FROM_LOOP where possible. Previously, the
optional-ness was a result of inner nestings gobbling up the
COME_FROM.

We'll probably want to go back and fix this up in Python2.

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.
