6a87ac0efb Rewrite the TrailingObjects template to provide two new features:
- 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.

6670ac798b Fix Visual C++ error C2248:
'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?

45f6b5bc69 Add a TrailingObjects template class.
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.
