Cleanup of SSE optimization files.

General cleanup of optimization files for x86/SSEx.
Renamed the opts_check_SSE2.cpp file to _x86, since it's not specific
to SSE2. Commented out the ColorRect32 optimization, since it's
disabled anyway, to make it more visible.
Also fixed a lot of indentation, inclusion guards, spelling,
copyright headers, braces, whitespace, and sorting of includes.
