Implement StmtReturn (#4960)

Browse source 
* Implement StmtPass

This implements StmtPass as `pass`.

The snapshot diff is small because pass mainly occurs in bodies and function (#4951) and if/for bodies.

* Implement StmtReturn

This implements StmtReturn as `return` or `return {value}`.

The snapshot diff is small because return occurs in functions (#4951)
