aobench on Parallella.
Based on Shodruky's mandelbrot example
How to build and run
Go to framebuffer mode(CTRL + ALT + F2)
Will render animation of aobench. After execution, you can go back to GUI by CTRL + ALT + F7
-O3 option doesn't work(seems causing stack overrun at runtime).
epiphany core doesn't have division, sqrt, etc in HW, thus we have to provide (approximate) functions of these for better performance.
