[Issue 5931] keyword new insists on calling a struct's (non-zero argument) constructor--in other words, it won't allow default initialization; also postblit this(this) constructor dosen't get called from "new <structname>(<struct_instance>)"

Post-blit is only called when you override the whole structure, as in:

----------------------------------------
import std.stdio;

struct S {
    this(this) {
        writeln("postblit");
    }
}

void main() {
    S s;
    S t;
    s = t;    // <-- call postblit on s.
}
----------------------------------------

Pointer-assignment will *not* call post-blit as you have not blitted
(memcpy-ed) anything.
