  Log Message:
  -----------
  [libc++] Remove some _LIBCPP_CXX03_LANG from iostreams headers.

With the STL containers, I didn't enable move operations in C++03 mode
because that would change the overload resolution for things that today
are copy operations. With iostreams, though, the copy operations aren't
present at all, and so I see no problem with enabling move operations
even in (Clang's greatly extended) C++03 mode.

Clang's C++03 mode does not support delegating constructors.
