Anton Bikineev cc7e74753a [CodeGenCXX] Treat 'this' as noalias in constructors
This is currently a clang extension and a resolution
of the defect report in the C++ Standard.

Differential Revision: https://reviews.llvm.org/D46441

Rafael Espindola c3cde36ead Output destructors and constructors in a more natural order.
With this patch we output the in the order
C2
C1

D2
D1
D0

Which means that a destructor or constructor that call another is output after
the callee. This is a bit easier to read IHMO and a tiny bit more efficient
as we don't put a decl in DeferredDeclsToEmit.

Douglas Gregor b14d123774 Give explicit template instantiations weak ODR linkage. Former
iterations of this patch gave explicit template instantiation
link-once ODR linkage, which permitted the back end to eliminate
unused symbols. Weak ODR linkage still requires the symbols to be
generated.

Douglas Gregor ee3f72299c Give explicit template instantiations weak linkage (but don't defer
them). Fixes PR6578.

John McCall 334ce7c1c4 Revert the ctor/dtor alias optimization for now; the buildbots can detect
some failure here that I can't.

John McCall 67cea74745 Emit complete constructors and destructors as aliases to base constructors
and destructors when the two entities are semantically identical, i.e. when
the class has no virtual base classes.  We only do this for linkage types
for which aliases are supported, i.e. internal and external, i.e. not linkonce.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
