Compiler-explorer: quick-bench.com integration

[mattgodbolt]

As discussed with @FredTingaud and now we have Google Benchmark available we should have bidirectional links to quick-bench.com :)

Maybe it's time to implement this like we did with cppinsights

[FredTingaud]

I'll have time to work on it and that is definitely something I want to see.

This was already implemented on the quickbench side of things by Fred.
Will see if I can figure out this React thing to allow links from our side of things.

Great stuff, thanks Partouf. I have a CE evening coming up to take a look (and might even have time tonight...)
