Begin working on flow analysis.
For now, variable and flow graph node maps are built.

Make the returned dag a linked list of root-nodes.
A dag can have mulitple "root" nodes (ie, nodes with no parents).

Handle attached identifier labels correctly.
I'd forgotten I had the prev field. Makes for much cleaner code.

Attach dags to statement blocks.
Now, if a dag is attached to a statement block, it will be included in the
flowgraph with that statement block.

Put the dags stuff into a qfcc sub-section.
Not much point writting docs if they can't be found.

Start work on building dags from basic blocks.
Doesn't compile and the design is in flux anyway, but I want to get back to
iqm.

Change dags from binary to trinary.
I'd forgotten some instructions take three inputs that can benefit from
CSE.

Initial support for basic block dags.
Currently, only dumping to dot, but that seems to be a very sensible place
to start: debug support.
