Subject: Add initial cut at CompilerInvocation::toArgs, which "serializes" the
 CompilerInvocation into a list of arguments which can be passed to clang-cc
 (eventually, clang -cc1).  - Unfortunately, this is currently a tedious and
 manual translation. Eventually it would be nice to automatically generate
 this code.
