I think we can close this bug. gcc-6 now compiles faster than gcc-5
and the resulting binary also runs slightly faster.
CXXFLAGS="-std=c++14 -w -Ofast" for all compilers
gcc-4.9: 24.199 compile tim

Well, to be fair one should compare -std=c++14 for all versions, else
you just measure the well known C++11 libstdc++ allocator overhead.
gcc-49(-std=c++14): 23.242 sec
gcc-5 (-std=c++14): 26.
