Subject: [PATCH] standalone: Fix several issues post script refactoring

- Add helptext for check_demos.sh
- Add back support for using debug NAC3 for running tests
- Output error message when argument is not recognized
- Fixed last non-demo script argument being ignored
- Add back SSE2 requirement to NAC3 (required for mandelbrot)
