Tracking issue for the type system redesign, described in this specification.
[x] Define new types: handshake::ChannelType and handshake::ControlType (bebfb02).
[x] Define new operations to manipulate these types: handshake::UnbundleOp (9fef8a5), handshake::BundleOp (9fef8a5), and handshake::ReshapeOp (6db1062).
[x] Redefine arith operations in Handshake to make them accept our custom types (9dbd9db adds a usable subset of the arith operations, implementation of currently missing operations is moved to a different issue: #102).
Refactor significantly the CfToHandshake conversion pass.
[x] First, a largely mechanical makeover (without using the new types) to avoid a MLIR dialect registration issue that arises non-deterministically when running it (582684a).
[x] Then, add type conversion logic to make it convert MLIR's standard types into our custom types (3aadbaf).
[x] Adapt all of our existing passes to the new type system (3aadbaf).
Refactor the Handshake-to-HW lowering flow.
[x] Add Handshake post-processing pass(es) that manipulate our types to make the conversion to HW and then RTL export easier (2082b20).
[x] Remove type conversion infrastructure from the HandshakeToHW conversion pass (now handled by the CfToHandshake conversion pass) (3aadbaf).
[ ] Add HW post-processing pass(es) to unbundle all channels into their individual signals (this will make the RTL export logic simpler) (moved to #139).
Backend changes.
[x] Most likely we will need to be able to fully encode a channel's characteristics in RTL parameters. Support for more complex RTL parameters that the ones we already have needs to be added (4e1c39f).
[ ] Define new components which are able to support more complex channels (moved to #140).
