[instcombine] Scalarize operands of vector geps if possible (#145402)
If we have a gep with vector indices which were splats (either constants
or shuffles), prefer the scalar form of the index. If all operands are
scalarizable, then prefer a scalar gep with splat following.
This does loose some information about undef/poison lanes, but I'm not
sure that's significant versus the number of downstream transformations
which get confused by having to manual scalarize operands.
