[SVE] Fix invalid use of VectorType::getNumElements() in PatternMatch
Summary:
Update cst_pred_ty to only work on FixedVectorType. It operates on
integers and integer vectors, and returns true if the predicate returns
true for all elements of the vector. This operation is not possible on
scalable vectors. Make this behavior explicit in the code and document
the fact that it only tests fixed width vectors.
