Keno Fischer ab41662e58 ConstantFolding: Don't crash when encountering vector GEP ...

ConstantFolding tried to cast one of the scalar indices to a vector
type. Instead, use the vector type only for the first index (which
is the only one allowed to be a vector) and use its scalar type
otherwise.

Fixes PR31250.
