<pre>Test case courtesy of Eli:
class DefaultedDefaultConstructor {
public:
bool hasValue;
bool value;
DefaultedDefaultConstructor() = default;
};
class NoDefaultConstructor {
public:
bool hasValue;
bool value;
};
DefaultedDefaultConstructor f(int x, int y);
bool g() { return f(5, 6).value; }
NoDefaultConstructor f2(int x, int y);
bool g2() { return f2(5, 6).value; }
MSVC generates the same code for g and g2, but clang returns
DefaultedDefaultConstructor indirectly.
I tested x86 and x64, and both are wrong, but we probably get it wrong for
arm64 and thumb as well.</pre>
