ead75d9434 (Reland)[mlir] Add a generic data-flow analysis framework
Removes one element of the pointer union to make it work on 32-bit
systems.

This patch introduces a generic data-flow analysis framework to MLIR. The framework implements a fixed-point iteration algorithm and a dependency graph between lattice states and analysis. Lattice states and points are fully extensible to support highly-customizable analyses.

This reverts commit 9dea11728340e54e1fde76320b61a559148c8a3e.
The PointerUnion assumes 3 available bits, which is not the case on 32-bit
machines.
