Tests pass for me on Cygwin g++ 6.3.0 (03/11/14/1z), clang++ 3.9.1
(03/11/14/1z), msvc-8.0, 10.0, 11.0, 12.0, 14.1.

The ensure_obj helper shouldn't be necessary here. The above tests also pass

+#define BOOST_TYPEOF(expr) boost::type_of::remove_cv_ref_t<decltype(expr)>

and the definition of ensure_obj removed.

I've also enabled Travis for typeof, so any future pushes in the PR should
be CI-tested.

Tests fail with msvc-14.1 /std:c++latest because of use of binder1st,
auto_ptr, unary_function and so on, but that's a separate issue and
unrelated to these changes, although we'll probably have to fix it at some
