Show note for type ascription interpreted as a constant pattern, not a new variable
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.

e489971902 Fix def-use dominance check
A definition does not dominate a use in the same statement. For example
in MIR generated for compound assignment x += a (when overflow checks
are disabled).
