- Implement support for the TensorFlow 'If' op, the first TF op definition.
- Fill in some missing basic infra, including the ability to split a basic block, the ability to create a branch with operands, etc.
- Implement basic lowering for some simple forms of If, where the condition is a zero-D bool tensor and when all the types line up. Future patches will generalize this.
There is still much to be done here. I'd like to get some example graphs coming from the converter to play with to direct this work.

This patch adds support for basic block arguments including parsing and printing.
In doing so noticed that `ssa-id-and-type` is undefined in the MLIR spec; suggested an implementation in the spec doc.

in a container automatically maintain their parent pointers, and change storage
from std::vector to the proper llvm::iplist type.

This is pretty much minimal scaffolding for this step. Basic block arguments,
instructions, other terminators, a proper IR representation for
blocks/instructions, etc are all coming.
