Sanjay Patel 7cd32419ab [InstCombine] avoid extra poison when moving shift above shuffle 
As discussed in D49047 / D48987, shift-by-undef produces poison,
so we can't use undef vector elements in that case..

Note that we need to extend this for poison-generating flags,
and there's a proposal to create poison from FMF in D47963,
