If source code is invalid, error recovery can lead to name lookup in a set containing invalid declaration. The lookup is stopped once found such declaration, but LookupResult object could remain in inconsistent state. Its destructor triggered a check, which caused assert violation.
This patch fixes PR16964 and PR12791.

Revert "DebugInfo: Remove explicit declaration-emissiong handling now that we have a more principled approach (the 'requires complete type' callback)"

This reverts commit r189013.

This is causing a segfault crash in a test case I have. Reverting while
I investigate the issue.

I tried to implement this properly in r189051, but I didn't have enough
test coverage.  Richard kindly provided more test cases than I could
possibly imagine and now we should have the correct condition.

This fixes pr13124.

From the discussion at
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-June/022606.html
we know that we cannot make funcions in a weak_odr vtable also weak_odr. They
should remain linkonce_odr.

The side effect is that we cannot emit a available_externally vtable unless we
also emit a copy of the function. This also has an issue: If codegen is going
to output a function, sema has to mark it used. Given llvm.org/pr9114, it looks
like sema cannot be more aggressive at marking functions used because
of vtables.

This leaves us with a few unpleasant options:

* Marking functions in vtables used if possible. This sounds a bit sloppy, so
  we should avoid it.
* Producing available_externally vtables only when all the functions in it are
  already used or weak_odr. This would cover cases like

--------------------
struct foo {
  virtual ~foo();
};
struct bar : public foo {
  virtual void zed();
};
void f() {
  foo *x(new bar);
  delete x;
}
void g(bar *x) {
  x->~bar(); // force the destructor to be used
}
--------------------------

and

----------------------------------
template<typename T>
struct bar {
  virtual ~bar();
};
template<typename T>
bar<T>::~bar() {
}

// make the destructor weak_odr instead of linkonce_odr
extern template class bar<int>;

void f() {
  bar<int> *x(new bar<int>);
  delete x;
}
----------------------------

These look like corner cases, so it is unclear if it is worth it.

* And finally: Just nuke this optimization. That is what this patch implements.

Patch by chris.wailes@gmail.com

Functions can now declare what state the consumable type the are returning will
be in. This is then used on the caller side and checked on the callee side.
Constructors now use this attribute instead of the 'consumes' attribute.
