Unnecessary heap allocation in mandelbrot/2.cs

[Ttxman]

Why is this here?

Programming-Language-Benchmarks/bench/algorithm/mandelbrot/2.cs

Line 52 in 1a0aea4

var ci = new Vector<double>(new[] { civ, civ, civ, civ });

Rest of the code assumes 256bit (4 doubles) vectors and
So this is equivalent of just calling

 var ci = new Vector<double>(civ); 

Just with heap allocation of new array each call :/

Same constructor overload new Vector<double>(0); (I would use Vector<double>.Zero but the performance impact will be negligible) is used in the zeroing of all other vectors so the heap allocation seems odd.
