[dev.typeparams] cmd/compile/internal/types2: implement type sets with term lists
This CL resolves several known issues and TODOs.
- Represent type sets with term lists and using term list abstractions.
- Represent Unions internally as a list of (syntactical) terms.
Use term operations to print terms and detect overlapping union
entries.
- Compute type sets corresponding to unions lazily, on demand.
- Adjust code throughout.
- Adjusted error check in test/typeparam/mincheck.dir/main.go
to make test pass.
