[NFC] Refactoring MeshToFlow pass out from patterns. (#17245)

This moves the pass out to the Transforms/ directory and separates the
pass logic from the patterns for consistency with all the other
conversions. This will also help us move around where the pass is run
and possibly merge it with the main ConvertToFlow pass by separating
lookup from channel materialization as we do with device globals. Such
refactorings will (likely) be required for proper multi-device
scheduling but this initial refactoring is just moving code around and
leaves the pass running where it does (during the input pipeline).

We could probably put the ConvertMeshToFlow pass in
InputConversion/Common/ today based on where it's invoked, but I feel
like input may be the wrong layer for it if we expect any global
optimization phase work to happen on the mesh dialect and we may want to
move it later. It depends on whether we treat the flow ops as the
optimization mechanism for any partitioning work we do during global
optimization.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.

Project Status

IREE is still in its early phase. We have settled down on the overarching infrastructure and are actively improving various software components as well as project logistics. It is still quite far from ready for everyday use and is made available without any support at the moment. With that said, we welcome any kind of feedback on any communication channels!

  • MLIR topic within LLVM Discourse: IREE is enabled by and heavily relies on MLIR. IREE sometimes is referred to in certain MLIR discussions. Useful if you are also interested in MLIR evolution.
