Anders Carlsson 9bd7d16440 When emitting the destructor for a class with a vtable, if we can determine 
that the destructor body is trivial and that all member variables also have either
trivial destructors or trivial destructor bodies, we don't need to initialize the
vtable pointers since no virtual member functions will be called on the destructor.

Fixes PR9181.

John McCall 5880fb8edf Only perform the null-initialization of an aggregate result of a message 
send if the receiver is null.  Normally it's not worthwhile to check this,
but avoiding the null-initialization is nice, and this also avoids nasty
problems where the null-initialization is visible within the call because
we use an aliased result buffer.  rdar://problem/9402992

Argyrios Kyrtzidis dd72aafffc Create proper Objective-C @encoding for C++ classes; fixes rdar://9357400. 
Go through and expand the members of bases into the encoding string (and encode the VTable as well).
Unlike gcc which expands virtual bases as many times as they appear in the
hierarchy, clang will only expand them once at the end, to reflect the actual layout.

Note that there doesn't seem to be a way to indicate in the encoding that
packing/alignment of members is different that normal, in which case
the encoding will be out-of-sync with the real layout.
If the runtime switches to just consider the size of types without
taking into account alignment, we could easily make padding explicit in the
encoding (e.g. using arrays of chars). The encoding strings would be
longer then though.

Also encode a flexible array member as array of 0 size, like gcc, not as a pointer.

Argyrios Kyrtzidis 7da04c6367 Emit an error when trying to @encode an incomplete type. 
There are APIs, e.g. [NSValue valueWithBytes:objCType:], which use the encoding to find out
the size of an object pointed to by a pointer. Make things safer by making it illegal to @encode
incomplete types.

Francois Pichet c2fac71c75 Revert 131347. It asserts if the specialization in within a class template: 
template<class U> 
struct X1 {
  template<class T> void f(T*);
  template<> void f(int*) { } 
};

Won't be so simple. I need to think more about it.
