[InstCombine][SSE4A] Remove broken INSERTQI range combining optimization 

As discussed in D13348 - the INSERTQI range combining code is wrong in that it confuses the insertion bit index with an extraction bit index.

The remaining legal combines are very unlikely (especially once we've converted to shuffles in D13348) so I'm removing the optimization.
