17f42e02a1 Revert r163298 "Optimize codegen for VSETLNi{8,16,32} operating on Q registers." 
Keep the integer_insertelement test case, the new coalescer can handle
this kind of lane insertion without help from pseudo-instructions.

6c822eea47 Optimize codegen for VSETLNi{8,16,32} operating on Q registers. Degenerate to a VSETLN on D registers, instead of an (INSERT_SUBREG (VSETLN (EXTRACT_SUBREG ))) sequence to help the register coalescer.
