  Log Message:
  -----------
  [ValueTracking][SVE] Fix isGEPKnownNonNull for scalable vector.

Summary:
DataLayout::getTypeAllocSize() return TypeSize. For cases where the
scalable property doesn't matter, we should explicitly call getKnownMinSize()
to avoid implicit type conversion to uint64_t, which is not valid for scalable
vector type.
