Clang does this in the driver. Why not Swift? Because (a) this is an
implementation detail that really only affects IRGen, and even then
somewhat incorrectly, and (b) Swift has a good handful of clients that
don't go through the driver to create an ASTContext (specifically, LLDB,
along with many of our testing tools).
