Eliminate redundancy of dup/idup

[kenji hara]

Yes, This works just as expected.

import std.stdio;
void main()
{
    char[] a = dup("Hello");
    string b = dup(a);
    writeln(a);  // prints "Hello"
    writeln(b);  // prints "Hello"
    assert(cast(void*)a.ptr !is cast(void*)b.ptr);  // elements are duplicated
}
