If you want to write a config.test to check if the compiler has enough support, 
I recommend taking code from tests/auto/other/compiler, maybe even share. That 
way, if we find later that the check is insufficient, we should update the unit 
test too.

Clang 3.6 results:
Totals: 63 passed, 0 failed, 1 skipped, 0 blacklisted
(the skip was "runtimeArrays", which was removed from C++14)

GCC 4.9 skips cxx14_constexpr, cxx14_aggregate_nsdmi, 

ICC 15 skips all the C++14 stuff

GCC 5 is running into a compilation error with variable templates. I'll need 
to investigate sometime before we add GCC 5 to the CI.
