Chandler Carruth b071036b7b As Doug pointed out (and I really should know), it is perfectly easy to 
make VariadicFunction actually be trivial. Do so, and also make it look
more like your standard trivial functor by making it a struct with no
access specifiers. The unit test is updated to initialize its functors
properly.

Chandler Carruth fd1f79871a Put the '*' in the right place in the unit test. Forgot to fix up this 
bit of style, sorry.

Chandler Carruth 1d47523a8e Add a generic collection of class templates to ADT for building 
variadic-like functions in C++98. See the comments in the header file
for a more detailed description of how these work. We plan to use these
extensively in the AST matching library. This code and idea were
originally authored by Zhanyong Wan. I've condensed it using macros
to reduce repeatition and adjusted it to fit better with LLVM's ADT.

Thanks to both David Blaikie and Doug Gregor for the review!
