* Match using isa
- This limits the rewrite pattern to ops defined in op registry but that is probably better end state (esp. for additional verification).

With the builder to construct the type on the Type, the appropriate mlir::Type can be constructed where needed. Also add a constant attr class that has the attribute and value as members.

* Allow multi input node patterns in the rewrite;
* Use number of nodes matched as benefit;
* Rewrite relu(add(...)) matching using the new pattern;
To allow for undefined ops, do string compare - will address soon!

Add convenience wrapper to make it easier to iterate over attributes and operands of operator defined in TableGen file. Use this class in RewriterGen (not used in the op generator yet, will do shortly). Change the RewriterGen to pass the bound arguments explicitly, this is in preparation for multi-op matching.
