3575 – CTFE: member structs not initialized correctly

This is a couple of cases I missed in my CTFE patches in DMD2.032.
Root cause: defaultInit for a struct is a VarExp, not a StructLiteral. This needs to be applied recursively. Patch: I've added a recursive defaultInitAsStructLiteral() to TypeStruct. It needs to be called from two places in interpret.c.
---------------------------------
struct SwineFlu {
 int a; int b;
}
struct Infection {
 SwineFlu y;
}
struct IveGotSwineFlu {
 Infection x;
 int z;
 int oink() { return x.y.a+10; } 
}
int quarantine() {
 IveGotSwineFlu d;
 return d.oink();
}
struct Mexico {
 Infection x;
 int z=2;
 int oink() { return z+x.y.b; }
}
int mediafrenzy() {
 Mexico m;
 return m.oink;
}
static assert( quarantine() == 10);
static assert( mediafrenzy() == 2);
