This required changing BindingPattern::name() to return `"_"` instead of nullopt when representing a `"_"` binding.
Semi-related drive-by fixes:
- Update BindingPlaceholderValue to expose a NamedEntity instead of a string name, and stop exposing its type.
- Drop the unused SourceLocation parameter of ValueEqual
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()`.

This starts detecting naming collisions as a consequence of being able to determine when the name is declared twice in a given scope.
