Sanjay Patel 26c119a9c2 [InstCombine] allow lengthening of insertelement to eliminate shuffles 
As noted in post-commit comments for D52548, the limitation on 
increasing vector length can be applied by opcode.
As a first step, this patch only allows insertelement to be
widened because that has no logical downsides for IR and has 
little risk of pessimizing codegen.

This may cause PR39132 to go into hiding during a full compile,
but that bug is not fixed.
