939a2b38a3 optimize/functions: fix ExtendedRosenbrock for BFGS test 
With the fused operation, grad diverges, resulting in a non-progression
of the location.

be8b0445de optimize/functions: fix BrownBadlyScaled for BFGS and LBFGS tests 
With the fused operation, f3 is calculated to -9e-17 rather than zero,
allowing another iteration, which fails to progress due to underflow.
