D2 changes! Removed druntime from the repository again.. Sorry :/ Updated the druntime port a bit, now requires druntime from trunk. Added info in runtime/README on how to get druntime from trunk. Added patch to add LDC support to druntime. Removed some debug logging from D2 builds. Fixed broken typeinfo for const/invariant in D2.

class A {
    int i;
    int l;
    this(bool b,bool b2=false) {
        if (b) this = new B;
        i = 4;
        if (b2) this = new C;
        l = 64;
    }
}
class B : A{
    this() {
        super(false);
    }
}
class C : A{
    this() {
        super(false);
    }
}
void main() {
}
