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!

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.

Fix two bugs with temporaries:
...
1. For
A f() {
return A();
}
we were incorrectly calling the A destructor on the returned object.
2. For
void f(A);
void g() {
A a;
f(a);
}
we were incorrectly not calling the copy constructor.

Unify the codepaths used to verify base and member initializers for explicitly
...
and implicitly defined constructors. This has a number of benefits:
1. Less code.
2. Explicit and implicit constructors get the same diagnostics.
3. The AST explicitly contains constructor calls from implicit default
constructors. This allows handing some cases that previously weren't handled
correctly in IRGen without any additional code. Specifically, implicit default
constructors containing calls to constructors with default arguments are now
handled correctly.
