When struct val field name equals constructor argument "ambiguous overload"

When struct val field name equals constructor argument "ambiguous overload"

```fs
open System

[]
type C =
val private x: int
new (x) = { x = x }

//error FS0041: A unique overload for method 'C' could not be determined based on type information
// prior to this program point. A type annotation may be needed. Candidates: C (), new : x:int -> C
let test = C(x = 0)
```

Changing `new (x)` to say `new (y)` (and its references) allows the resolution to succeed. ¯\\_(ツ)_/¯
