Collection expressions: inapplicable overloads considered in overload resolution

[cston]

Version Used: d838fac

Steps to Reproduce:

F([1, 2, 3]) below is reported as ambiguous, even though only one overload is applicable.

class Program
{
    static void F(string[] arg) { }

    static void F(int[] arg) { }

    static void Main()
    {
        F([1, 2, 3]); // error CS0121: ambiguous between 'F(string[])' and 'F(int[])'
    }
}

Expected Behavior:
Compiles successfully.

Relates to test plan #66418

Actual Behavior:
Error reported: error CS0121: ambiguous between 'F(string[])' and 'F(int[])'
