Summary:
This patch fix the following issues with visitExtractElementInst:
1. Restrict VectorUtils::findScalarElement to fixed-length vector.
For scalable type, the number of elements in shuffle mask is
unknown at compile-time.
2. Fix out-of-range calculation for fixed-length vector.
3. Skip scalable type when analysis rely on fixed number of elements.
4. Add unit tests to check functionality of extractelement for scalable type.
