[GlobalISel][IRTranslator] When translating vector geps, splat the base pointer if required.

We can have geps that have a scalar base pointer, and a vector index value, which
means that the base pointer must be splatted into a vector of pointers.

This fixes crashes on arm64 GlobalISel with optimizations enabled.
