Fix the naive opcode checks.
Confusing . with .=, and < and <= with more <MOVE etc isn't good.

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

Use value for pointer operands.
This allows daglabels on pointer operands without a redundant daglabel
pointer.

Generate only one daglabel for value operands.
As each value is now unique, their labels can also be unique, which will
improve CSE.

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

Fix the completely bogus handling of "x" in dag creation.
That made a complete mashup of attached identifiers :P

Start actually trying to build dags.
Temporary variables aren't being handled correctly (treated as constants),
but it looks like a good start.

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.

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