I was trying to move the "needs exception" to clang, but there is a
problem. What should we do when there is a C and a C++ file in the
same clang-cc invocation? Currently

clang-cc foo.c bar.cc

will compile bar.cc with exception and foo.c without.

Is the current patch (with the logic in clang-cc) ok?
