The recent fix (https://reviews.llvm.org/D42100) for vector stores of non byte-sized elements lacked consideration of endianness.

After discussion it was agreed that the order of the elements in the built integer should be reversed for Big-Endian targets, which is what this patch is aimed to do.

The SystemZ (Big-Endian) tests are updated as well.
