Nicolai Haehnle 77841b159a TableGen: Type-check BinOps 
Additionally, allow more than two operands to !con, !add, !and, !or
in the same way as is already allowed for !listconcat and !strconcat.

Nicolai Haehnle 6c11865638 TableGen: Add !dag function for construction 
This allows constructing DAG nodes with programmatically determined
names, and can simplify constructing DAG nodes in other cases as
well.

Also, add documentation and some very simple tests for the already
existing !con.
