Windows /O3 flag; stabilizer micro-optimations

Mostly, this release is for metadata including README. However, Windows builds now use the /O3 optimization flag properly. (We did not previously notice that the build logs on Windows indicated we had passed the argument incorrectly from CMake build.) Minor micro-optimizations have also been made in stabilizer simulation.
