  [libc++] Fix LWG3557 "static_cast expression in convertible_to has the wrong operand"

I think the code change is unobservable, so we could just close this as
"Nothing To Do" instead; but it seems appropriate to follow the Standard's
wording here as closely as possible.

  Log Message:
  -----------
  [libc++] Make C++03 reference_wrapper more like C++11.

Remove a bunch of LIBCPP_CXX03_LANG. This is the result of a
rabbithole to re-eliminate the workaround I introduced into
std::cref in D117953. It turns out that Clang's C++03 mode
(the only compiler we care about C++03 for) now supports all
the things we were originally eschewing via LIBCPP_CXX03_LANG;
we can fully support these reference_wrapper features in
C++03 mode, and un-XFAIL the relevant tests.

Drive-by constexprify a few more tests.
