This doesn't actually use the results of name resolution, but it does verify that they are present.
Also ensures that name resolution and type checking are applied to deduced function parameters and the implicit call to `Main()`.

#939 switch to `Main`, but #919 predated it and didn't get updated
before merging. Its tests passed on the PR branch as a consequence, but
failed when landed.
This just updates the test cases. Trivial fix forward.
This starts detecting naming collisions as a consequence of being able to determine when the name is declared twice in a given scope.
