Use builtin overflow functions of Clang and GCC (WIP, RFC)
This only works with recent Clang and GCC 5.0. Currently it doesn't work because __has_builtin can't be defined. This is totally ugly. But we can't reliably detect whether we can use the builtins from Nim, especially with cross-compiling where the user may be using an older compiler version. Switching this on/off manually with a define seems weird as well, this should work automatically.
