title: how to use SSE to process array of ints, using a condition
body: <p>I'm new to SSE, and limited in knowledge. I'm trying to vectorize my code (C++, using gcc), which is actually quite simple. 
  I have an array of unsigned ints, and I only check for elements that are >=, or &lt;= than some constant. As result, I need an array with elements that passed condition.
  I'm thinking to use 'mm_cmpge_ps' as a mask, but this construct work over floats not ints!? :(</p>
  
  <p>any suggestion, help is very much appreciated.</p>
