Detailed Description

Removes calyx::CombGroupOps which are unused.

These correspond to combinational groups created during op building that, after conversion, have either been inlined into calyx::GroupOps or are referenced by an if/while with statement. We do not eliminate unused calyx::GroupOps; this should never happen, and is considered an error. In these cases, the program will be invalidated when the Calyx verifiers execute.
