-The 1) marked instructions could be scheduled better for reduced register 
-pressure.  The scheduling issue is more pronounced without -static.
-
-The 2) marked instructions are the lowered form of the 1,undef,3,4 
-shufflevector.  It seems that there should be a better way to do it :)

 If shorter, we should use things like:
 movzwl %ax, %eax
 instead of:
