Move tile and distribute out of Flow dialect (#8362)

Currently the IREE compilation flow tiles and distributes at the Flow
level. This leads to a very early decision being made on what to
distribute, and is a phase ordering issue. It is better to have
backends decide how to tile and distribute ops in a dispatch. This
would allow

Different backends to make different decisions on what parallel
dimensions to distribute.
Allow backends to do things like interchange the loops before
distribution that helps improve performance in some cases.
It also simplifies the code a lot. This particular change is mostly
NFC since it removes the tile and distribute at flow level, and adds a
pass to do the same tile and distribute as the first step in during
translation. Issue #8363 captures the next steps involved to complete
the transition to get to a overall better state.

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!
