Xojoscript math performance relatively poor in 2018R1

The math performance of Xojoscript in 2018 Release 1.1 has decreased significantly compared to 2017R3, especially when transcendental functions are involved. The results are shown below where higher is better (think in terms of operations per unit time). The biggest hit is in complex math which relies heavily on transcendental math functions such as sin(), cos(), sinh() and cosh(). However, general math has also decreased in speed.
(Note that compiler optimization level = 0 is normal and level=2 is high.)
