This patch is to fix two issues
   - PromoteSplat generate the same code for splats of an element  to  
v8i16 and v16i8 irregardless of which element to splat.  We should  
generate slightly different sequences depending on which element to  

  - In LowerVECTOR_SHUFFLEv8i16, if we have a shuffle that requires  
lowering to extract and insert between two different vectors, we can  
an assert in the compiler.  We were accessing a non existent mask  

Please let me know if you have any comments,
