[webkit-dev] C++17 is here. Should we use it?

[Yusuke SUZUKI]

I really like C++17, `if with initializer` is super great. Awesome
constexpr lambda and if.
And std::optional and std::variant...

However, IIRC, WebKitGTK+ needs to support some old compilers.
The current GCC support is 5.0.0, which is recently upgraded.
https://bugs.webkit.org/show_bug.cgi?id=174155

Possibly, mcatanzaro and clopez know much about WebKitGTK+ compiler
dependencies.

Yusuke Suzuki
