Associative arrays with BigInts as keys are unusable:

import std.bigint, std.stdio;
void main()
{
    int[BigInt] a;
    a[BigInt(3)] = 3;
    a[BigInt(3)] = 4;
    writeln(a);
}

Prints:

[3:3, 3:4]

Apparently duplicate keys.

Probably related to Issue 8435.

I thought this was a consequence of Issue 3789 because BigInt is a struct
containing a string. But that was resolved recently, and this bug still appears
in 2.063 beta.
