  Log Message:
  -----------
  [ConstantFold][SVE] Fix constant fold for FoldReinterpretLoadFromConstPtr.

Summary:
Bail out early for scalable vectors. As global variables are not expected
to be scalable.

Use explicit call of getFixedSize() to assert on places where scalable size
doesn't make sense.
