SL-47720 Crash on startup due to SSE instructions. Disable SSE code generation on Windows build. This prevents global constants from being initialized with SSE instructions. We can use the SSE code on Intel Mac (since they all support SSE) and if we enable SSE compilation for the entire Windows viewer. Reviewed by Kelly.
