Initializer (InitializerExpressionSyntax) is ignored for value types

[adrianoc]

No code is generated for the object initializer ( { Name = "A", Value = 42 })

using System;

var x = new Bar { Name = "A", Value = 42 } );

struct Bar
{
      public string Name {get; set;}
      public int Value {get; set;}
}

add extra tests to cover the following scenarios:

struct S
{
	public int Value { get; set; }
	public static bool operator>(in S l, in S r) => false;
	public static bool operator<(in S l, in S r) => false;
}

class Foo
{
	S TernaryOperators(int i) =>  i == 2 ? new S { Value = i } : new S { Value = i };

	S GetArrow() => new S { Value = 42 };
	S GetReturn() { return new S { Value = 42 }; }

	int X(int[] a) => a[ new S { Value = 1 } .Value ];
	
	bool P(int i) => new S { Value = 2} < new S { Value = 3 };
}
