Move new test cases into the "tricky" section as many compilers can't handle them.

Revert previous change that used std::is_convertible on GCC as it breaks code prior to gcc-4.7.
Fix MSVC intrinsic to handle function types better.
Filter out rvalue-refs from is_function.
Partially apply patch from #7251 to make is_convertible behave more according to C++11.
Refs #7251.
