Maintain a mapping between funcOp input arguments and the port index which the argument will eventually map to.
Maintain a mapping between funcOp output indexes and the component output port index which the return value will eventually map to.
Maintain a mapping between an external memory argument (identified by a memref) and eventual component input- and output port indices that will map to the memory ports. The pair denotes the start index of the memory ports in the in- and output ports of the component. Ports are expected to be ordered in the same manner as they are added by calyx::appendPortsForExternalMemref.
Create I/O ports. Maintain separate in/out port vectors to determine which port index each function argument will eventually map to.
Single-port arguments
We've now recorded all necessary indices. Merge in- and output ports and add the required mandatory component ports.
Create a calyx::ComponentOp corresponding to the to-be-lowered function.
Mark this component as the toplevel if it's the top-level function of the module.
Store the function-to-component mapping.
Rewrite funcOp SSA argument values to the CompOp arguments.
