libstdc++'s <cstdalign> #includes <stdalign.h> and expects it to guard against being included in C++. Don't define alignof or alignas in this case. Note that the C++11 standard is broken in various ways here (it refers to the contents of <stdalign.h> in C99, where that header did not exist, and doesn't mention the alignas macro at all), but we do our best to do what it intended. llvm-svn: 175708

Add tests that build modules for our builtin headers, and fix two buglets exposed by doing so. llvm-svn: 178736
