[SVE] Make VectorType::getNumElements() complain for scalable vectors

Authored by ctetreau on Apr 21 2020, 10:41 AM.



Piggy-back off of TypeSize's STRICT_FIXED_SIZE_VECTORS flag and:

  • if it is defined, assert that the vector is not scalable
  • if it is not defined, complain if the vector is scalable
