Since at least the C++11 standard insert iterators are specified
as having ::reference typedef void. Libc++ was not doing that.
This patch corrects the typedef.
This patch changes the std::iterator base class of insert_iterator,
front_insert_iterator and back_insert_iterator. This should not
be an ABI breaking change.

Quite a few libcxx tests seem to follow the format:
#if _LIBCPP_STD_VER > X
// Do test.
#else
// Empty test.
#endif
We should instead use the UNSUPPORTED lit directive to exclude the test on
earlier C++ standards. This gives us a more accurate number of test passes
for those standards and avoids unnecessary conflicts with other lit
directives on the same tests.
