The current integer widening does not support rewriting partial split slices in rewriteIntegerStore (and rewriteIntegerLoad). This patch adds explicit checks for this case in isIntegerWideningViableForSlice. Before r322533, splitting is allowed only for the whole-alloca slice and hence the above case is implicitly rejected by another check `if (DL.getTypeStoreSize(ValueTy) > Size)` because whole-alloca slice is larger than the partition.
