Comment at: clang/include/clang/Lex/Preprocessor.h:120
+/// callback that records tokens.
+enum class TokenSource {

This is supposed to provide enough information to distinguish token from an
intermediate macro expansion from a token of a final expanded stream.
It's not very well thought-through, though, the final set of enum values will
definitely end up being different.
