cd6a50f3e5 Make copy assignment operator synthesis not explode for classes with complex 
or non-record aggregate members.

It might be worth spending some time to optimize this code (and the parallel
code for copy constructors) to memcpy in larger chunks, rather than copying
one member at a time.  Not sure exactly how beneficial that would be, but
it seems like could help for large classes with, for example, a vtable pointer
forcing the generation of a copy constructor.

8174f2c23c Work-in-progess rewrite of thunks: move thunk generation outside of vtable 
generation, and make sure we generate thunks when the function is defined
rather than when the vtable is defined.

ce460529c0 When generating a virtual destructor, don't try to make a virtual call to the base class destructor because then we'll just re-enter the same destructor! 
This was done to fix PR5619, so I went ahead and passed a dummy VTT pointer for now.

84a7e347bf Simplify and fix up the handling of implicit constructors, copy assignment 
operators, and destructors.  Avoids generating declarations/definitions of
trivial constructors/destructors, and makes sure the trivial copy assignment
operator is generated when necessary.

3c9beab48a Handle references correctly when synthesizing copy constructors. 
With this change, the clang-on-clang test result is now

Expected Passes    : 224
Unexpected Failures: 37

Which means that we can compile over 80% of clang with clang! :)

b572c92674 PR5483: Generate missing form of destructor when it is virtual. (Someone

fb4dda4fed Instead of storing CXXMethodDecls in the vtable builder, store GlobalDecls so we can represent both the complete and deleting destructors. Also, when encountering a destructor decl, emit entries for both the complete and deleting destructors. Mike, please review. 
With this change, FileCheck builds and runs the clang test suite without failures!

e828c36933 Add a special BuildVirtualCall that's going to be used for building calls to destructors. This is needed because when compiling: 
struct A {
	virtual ~A();
};

void f(A* a) {
	delete a;
}

A's deleting destructor should be called.
