-------
In LLVMDC we fixed this_14_G/H by making the "constructors/destructors are only
for class definitions" error fatal. Otherwise you get a segfault around func.c
line 908 trying to access the InvariantDeclaration of the AggregateDeclatation*
ad that is zero.

Verify isThis() in addPostInvariant() and addPreInvariant().

This patch fixes G/H while handling errors normally.  All of the other
is*Invariant() methods check for ad, but static contructors and desctrutors
assume it's there, seemingly.

Validate that a static destructor has a parent.

This fixes this_14_I.  It just adds a clause, similar to the one for static
constructors, for static destructors.  This throws a very similar error and
doesn't crash.

Another example of 14G/14H, from bug 1533. [Unknown]'s patch fixes this, but
does result in one of the error messages having no line number.
---
template T(){
   this(int i){}  // causes 14G segfault
  ~this() {}     // causes 14H segfault
}

struct C{
   void foo(){
        bar();
        this.t(7);
   }
   mixin T!() t;
}

Fixed DMD2.030 and 1.045.
The segfault bug in 14G and 14H is fixed, as are all of the ICE bugs. 14G has
one error without line number ("Error: 'this' is only defined in non-static
member functions, not this") but since it comes after errors with line numbers,
it's trivial.
