Switch CallArgList from an std::pair to a new CallArg struct (which will eventually gain more members). Working towards modifying call emission to avoid unnecessary copies.

Fully implement delegating constructors!
...
As far as I know, this implementation is complete but might be missing a
few optimizations. Exceptions and virtual bases are handled correctly.
Because I'm an optimist, the web page has appropriately been updated. If
I'm wrong, feel free to downgrade its support categories.

Cut down unnecessary zero'ing when value-initializing arrays of C++ objects.
...
-C++ objects with user-declared constructor don't need zero'ing.
-We can zero-initialize arrays of C++ objects in "bulk" now, in which case don't zero-initialize each object again.

Make yet another placeholder type, this one marking that an expression is a bound
...
member function, i.e. something of the form 'x.f' where 'f' is a non-static
member function. Diagnose this in the general case. Some of the new diagnostics
are probably worse than the old ones, but we now get this right much more
universally, and there's certainly room for improvement in the diagnostics.

If there's an invoke destination, we should use invoke instead of call when calling the __cxa_bad_typeid function. Fixes PR7400.

CodeGenFunction::EmitDynamicCast always return null or throw a bad_cast
exception.

PHINode::Create() giving the (known or expected) number of operands.

Instead of storing an ASTContext* in FunctionProtoTypes with computed noexcept specifiers, unique FunctionProtoTypes with a ContextualFoldingSet, as suggested by John McCall.

Propagate the new exception information to FunctionProtoType.
...
Change the interface to expose the new information and deal with the enormous fallout.
Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications.
Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support.

An operator new with an empty exception specifier returns null on a bad
...
allocation and therefore requires a null-check. We were doing that, but
we weren't treating the new-initializer as being conditionally executed,
which means it was possible to get ill-formed IR as in PR9298.

Convert the exception-freeing cleanup over to the conditional cleanups code,
...
fixing a crash which probably nobody was ever going to see. In doing so,
fix a horrendous number of problems with the conditional-cleanups code.
Also, make conditional cleanups re-use the cleanup's activation variable,
which avoids some unfortunate repetitiveness.

Add support for explicit constructor calls in Microsoft mode.
...
For example:
class A{
public:
A& operator=(const A& that) {
if (this != &that) {
this->A::~A();
this->A::A(that); // <=== explicit constructor call.
}
return *this;
}

More work will be needed to support an explicit call to a template constructor.
