  -----------
  [InstSimplify][SVE] Fix SimplifyInsert/ExtractElementInst for scalable vector.

Summary:
For scalable vector, index out-of-bound can not be determined at compile-time.
The same apply for VectorUtil findScalarElement().

Add test cases to check the functionality of SimplifyInsert/ExtractElementInst for scalable vector.
