Given the code
```rust
pub fn main() {
const y: i32 = 4;
let y: i32 = 3;
}
```
`y` in the let binding is actually interpreted as a constant pattern
and is not a new variable, causing confusing diagnostics about
refutable patterns in local binding.
This commit extends the note for type ascription as a constant pattern
to `AscribeUserType` patterns as well.
