Philip Reames 3116bccced [SimplifyDemandedVec] Strengthen handling all undef lanes (particularly GEPs) ...

A change of two parts:
1) A generic enhancement for all callers of SDVE to exploit the fact that if all lanes are undef, the result is undef.
2) A GEP specific piece to strengthen/fix the vector index undef element handling, and call into the generic infrastructure when visiting the GEP.

The result is that we replace a vector gep with at least one undef in each lane with a undef.  We can also do the same for vector intrinsics.  Once the masked.load patch (D57372) has landed, I'll update to include call tests as well.
