Rearrange tests

[dkarrasch]

This brutally splits the triangular tests in two parts, and creates a dedicated test file for unitful tests. That should spread the load more evenly among several workers, when present.

To the best of my knowledge, this doesn't change any test overall. Mostly, this is copy-paste.

The unitful tests take off some heavy load from the bidiag.jl test suite, and the triangular.jl tests include only the initial big (nested) loops. All other parts are moved to triangular2.jl.

Hm, I missed to check upfront. So the triangular split doesn't yield much, the first block is the very dominant part, so we might as well keep the triangular tests as is. Though any reduction of its runtime is welcome, since this worker runs from start to end and determines the total runtime. I'll check the effect of removing the unitful tests from bidiag.jl tomorrow.

This looks much much better now! Comments welcome.
