Instcombine prefers this canonical form (see getPreferredVectorIndex), as does IRBuilder when passing the index as an integer so we may as well use the prefered form from creation. NOTE: All test changes are mechanical with nothing else expected beyond a change of index type from i32 to i64. Differential Revision: https://reviews.llvm.org/D140983
