  [SLP] Protect against scalable vector users.

We started seeing a crash after 8a0bfe490592de3df28d82c5dd69956e43c20f1d that
the user could be scalable, meaning the typesize is scalable and an implicit
convertion to uint64_t could be performed. Protect against that by making sure
the users type is not scalable.
