MSVC appears to be getting confused as to whether OverloadToken is
supposed to be public or not.
This was discovered by code in Swift, and has been reported to
microsoft by hughbe:

No functionality change intended.

Summary:
This change fixes issues with `LLVM_CONSTEXPR` functions and
`TrailingObjects::FixedSizeStorage`. In particular, some of the
functions marked `LLVM_CONSTEXPR` used by `FixedSizeStorage` were not
implemented such that they evaluate successfully as part of a constant
expression despite constant arguments.
This change also implements a more traditional template-meta path to
accommodate MSVC, and adds unit tests for `FixedSizeStorage`.
Drive-by fix: the access control for members of `TrailingObjectsImpl` is
tightened.

compiler-specific issues. Instead, repeat an 'operator delete' definition in
each derived class that is actually deleted, and give up on the static type
safety of an error when sized delete is accidentally used on a type derived
from TrailingObjects.

MSVC bug.
This fixes undefined behavior in C++14 due to the size of the object being
deleted being different from sizeof(dynamic type) when it is allocated with
trailing objects.
MSVC seems to have several bugs around using-declarations changing the access
of a member inherited from a base class, so use forwarding functions instead of
using-declarations to make TrailingObjects::operator delete accessible where
desired.

-fsized-deallocation. Disable sized deallocation for all objects derived from
TrailingObjects, as we expect the storage allocated for these objects to be
larger than the size of their dynamic type.

Previously, the code enforced non-decreasing alignment of each trailing
type. However, it's easy enough to allow for realignment as needed, and
thus avoid the developer having to think about the possiblilities for
alignment requirements on all architectures.
(E.g. on Linux/x86, a struct with an int64 member is 4-byte aligned,
while on other 32-bit archs -- and even with other OSes on x86 -- it has
8-byte alignment. This sort of thing is irritating to have to manually
deal with.)

- Automatic alignment of the base type for the alignment requirements
of the trailing types.
- Support for an arbitrary numbers of trailing types, instead of only
1 or 2, by using a variadic template implementation.
Upcoming commits to clang will take advantage of both of these features.

'llvm::TrailingObjects<`anonymous-namespace'::Class1,short,llvm::NoTrailingTypeArg>::additionalSizeToAlloc' :
cannot access protected member declared in class
'llvm::TrailingObjects<`anonymous-namespace'::Class1,short,llvm::NoTrailingTypeArg>'
I'm not sure how this compiles with gcc.
Aren't protecteded members accessible only with protected or public inheritance?

This is intended to help support the idiom of a class that has some
other objects (or multiple arrays of different types of objects)
appended on the end, which is used quite heavily in clang.
