Update LinearAlgebra for Julia 0.7

[diegozea]

This solves one of the TODO annotated tests in arithmetic.

Hint on the others: I saw that others TODO tests are failing because of transpose and permutedims, that were changed in Julia 0.7.

Cheers,

Now there are very few things to solve :)

FYI I am trying to see if we can move LinearAlgebra stuff to parts in the code that are loaded only when LinearAlgebra is used, see #67, and similarly for other library stuff that has been moved out of julia Base.

But the latest Require works differently than before, and the discussion there is too convolved for me to follow.

I think that it's ok to depend on modules from the standard libraries, e.g. LinearAlgebra and Random, because they are shipped with Julia. But, I agree with you that Requires.jl will be useful for things that are now on external libraries. I haven't used Requires on Julia 0.7 yet, but I can try for the external libraries. What do you think it's still needed to tag a NamedArrays version for 0.7?

There still are a number of TODOs in the test,

• convert
• sort
• broadcast
  I would be less worried about the linear algebra stuff.
