In this patch, it permits load/store/alloca struct with all the same
scalable vectors. We use TypeSize to represent the size of struct and
use StackOffset to represent the element offsets within the struct.
TypeSize only has one dimension, either Fixed or Scalable. That is why
we could not mix scalar and scalable vector within the struct.
