Fixed and refactored profiler options handling

- extracted profiler options in a separate class
- switched from system property reading to command line arguments
- added profile based compilation options to CompilerOptions
- removed no longer used kProfile compilation filter
- optimize dex files only if the profiler is enabled
- clean up unused arguments
