This is just an artifact from `index::generateUSRForDecl()` expecting a `SmallVectorImpl<char> &` as it's buffer. In the very beginning, the constructor of this class took a `FunctionDecl` and generated the USR into this field. 

This and every other data structure used needs to be revisited throught these source files once again before the patch is finalized.
