Parameterized unittests and benchmarks (aka quickfix + benchmark) PR 2995

[Robert burner Schadek via Digitalmars-d]

Everybody is talking about benchmarks and making code faster, yet 
phobos is still lacking any long term benchmark gathering and 
monitoring solution.

PR https://github.com/D-Programming-Language/phobos/pull/2995 
provides all that, and is done some time now. It will give us 
pretty pictures we can put on the webpage.
These will show how awesome phobos already is, and how much we 
improve performance wise with time progressing.

Please have a look, and let us make phobos the most benchmarked 
library out there.
