Chris Lattner 5d3919d5f9 move an optimization for memcmp out of simplifylibcalls and into
SDISel.  This optimization was causing simplifylibcalls to 
introduce type-unsafe nastiness.  This is the first step, I'll be 
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.
