Summary

Fewer copies in tensor factorizations and contractions: a backend now declares whether its matricized form is a view, so a factorization runs in the operand's own storage and hands its buffer to the output rather than copying in and back out.

Breaking: matricize goes through ismatricizeview, matricizeview and matricizecopy, replacing matricizekind and matricizepermaliases.

Fewer copies in tensor factorizations and contractions: a backend now declares whether its matricized form is a view, so a factorization runs in the operand's own storage and hands its buffer to the output rather than copying in and back out.

Breaking: `matricize` goes through `ismatricizeview`, `matricizeview` and `matricizecopy`, replacing `matricizekind` and `matricizepermaliases`.

Also restores precompilation on Julia LTS.
