<pre>Currently, Darwin constructs the header search paths in cc1. For this to work,
it needs information about the C++ STL. This is solved by passing down the
-stdlib argument to cc1.
ToolChain::AddClangCXXStdlibIncludeArgs states that this solution is legacy.
Instead, Darwin::AddClangCXXStdlibIncludeArgs should be implemented, maybe
similar to Linux::AddClangCXXStdlibIncludeArgs.
This also introduces problems with the test Driver/darwin-stdlib.cpp which
fails if CLANG_DEFAULT_CXX_STDLIB and will therefore shortly be XFAILed in that
case.</pre>
