Under -fms-extensions, only inject a friend tag name when we didn't see a tag with that name in an enclosing scope.
...
r177473 made us correctly consider only those declarations in the
enclosing namespace scope when looking for a friend declaration. Under
ms-extensions mode, where we do some level of friend injection, this
meant that we were introducing a new tag type into a different scope
than what Microsoft actually does. Address this by only doing the
friend injection when we didn't see any tag with that name in any
outer scope. Fixes <rdar://problem/14250378>.

Disallow reinterpret_cast from pointer to bool on Windows
...
This became allowed by accident in r131201, but triggers an assert.
That patch added an exception to allow conversion from pointers to
narrow integral types for MSVC compatibility. However, a pointer can
already be converted to bool in a civilized manner; allowing conversion
via reinterpret_cast is a bad idea.
Fixes PR16222.

Accept over-qualified constructor in MSVC emulation mode
...
MSVC accepts this:
class A {
A::A();
};
Clang accepts regular member functions with extra qualification as an MS
extension, but not constructors. This changes the parser to defer rejecting
qualified constructors so that the same Sema logic can apply to constructors as
regular member functions. This also improves the error message when MS
extensions are disabled (in my opinion). Before it was:
/Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers
A::A();
~~~~ ^
1 error generated.
After:
/Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A'
A::A();
~~~^

Emulate a MSVC bug where if during an using declaration name lookup, the declaration found is unaccessible (private) and that declaration was bring into scope via another using declaration whose target declaration is accessible (public) then no error is generated.
...
Example:
class A { public: int f(); };
class B : public A { private: using A::f; };
class C : public B { private: using B::f; };
Here, B::f is private so this should fail in Standard C++, but because B::f refers to A::f which is public MSVC accepts it.
