Get rid of a memory allocation on each call to the getXXXMetadata functions. We were using std::function that allocated memory. Unfortunately c++ lambdas don't have a type so I had to make the function findOrAdd templated on the type of the callback. This is not a big deal since the class is already templated and there is a single call site. Swift SVN r23919
