Test case for Brent solver. Because Brent-Dekker is guaranteed to converge in less than the default maximum iteration count due to bisection fallback, it is quite hard to debug. I include measured iteration counts plus one in order to detect regressions. On average Brent-Dekker should use 4..5 iterations for the default absolute accuracy of 10E-8 for sinus and the quintic function around zero, and 5..10 iterations for the other zeros.
