Mogball d80c271c8a [mlir] An implementation of dense data-flow analysis ...

This patch introduces an implementation of dense data-flow analysis. Dense
data-flow analysis attaches a lattice before and after the execution of every
operation. The lattice state is propagated across operations by a user-defined
transfer function. The state is joined across control-flow and callgraph edges.

Thge patch provides an example pass that uses both a dense and a sparse analysis
together.
