[Issue 2834] Struct Destructors are not called by the GC, but called on explicit delete.

One case where struct destructors are not called, in this situation it seems
simpler for the GC to know what destructors to call:


import core.memory: GC;
import core.stdc.stdio: printf;
struct Foo {
    int x;
    this(int xx) { this.x = xx; }
    ~this() { printf("Foo dtor x: %d\n", x); }
}
void main() {
    Foo[] a;
    a.length = 2;
    a[0].x = 1;
    a[1].x = 2;
    // delete a;
}


(I am not sure, but a type information can be useful in arrays, maybe to fix
bug 2095 too.)
