[InstCombine] Handle vector gep with scalar argument in evaluateInDifferentElementOrder

Summary:
This fixes PR41270.

The recursive function evaluateInDifferentElementOrder expects to be called
on a vector Value, so when we call it on a vector GEP's arguments, we must
first check that the argument is indeed a vector.
