  Log Message:
  -----------
  Enable concatenation of predefined identifiers

Predefined identifiers like __FUNCTION__ are treated like string
literals in MSVC, which means they can be concatentated together with
an adjacent string literal. Clang now supports this behavior as well,
in Microsoft extensions mode.
