IREE Python Sandbox

This directory contains various integration-oriented Python utilities that are not intended to be a public API. They are, however, useful for lower level compiler interop work. And of course, they are useful since we presently lack a real API :)

We're still untangling build support, jupyter integration, etc for OSS builds. Stand by.

Issues:

• This is called pyiree vs iree to avoid pythonpath collisions that tend to arise when an iree directory is inside of an iree directory.
• The above could be solved in the bazel build by making iree/bindings/python its own sub-workspace.
• However, doing so presently breaks both flatbuffer and tablegen generation because of fixes needed to those build rules so that they are sub-worksapce aware.
