4857: Fix invalid shorthand initialization diagnostic for tuple structs r=jonas-schievink a=OptimalStrategy

Initializing tuple structs explicitly, like in the example below, produces a "Shorthand struct initialization" diagnostic that leads to a compilation error when applied:
```rust
struct S(usize);

fn main() { 
    let s = S { 0: 0 };  // OK, but triggers the diagnostic
    // let s = S { 0 };  // Compilation error
}
```

This PR adds a check that the field name is not a literal.
