Cleanup of SSE optimization files.

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.

This is a first step in cleanup of x86 optimization files.

Before submitting this to the CQ, can you please add
  https://codereview.chromium.org/265513005/
to tools/chromium/chrome_changes ?

This lets us track the changes needed to keep Chromium building when we modify
Skia.  Here we just need to update the build system for the renamed file.
