Fix invalid shorthand initialization diagnostic for tuple structs #4857

Initializing tuple structs explicitly, like in the example below, produces a "Shorthand struct initialization" diagnostic that leads to a compilation error when applied:

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.
