3ee06ec52f Fix real schur and polynomial solver. 
For certain inputs, the real schur decomposition might get stuck in a cycle.
Exceptional shifts are supposed to knock us out of that - but previously
they were only ever applied at iteration 10 and 30, which doesn't help if
the cycle starts after cycle 30.  Modified to apply a shift every 16 iterations
(for reference, LAPACK seems to do it every 6 iterations).

Also added an assert in polynomial solver to verify that the schur decomposition
was successful.

Fixes #2633.

42b04a08c4 Fix preshear transformation. 
Fixes #2777.  The `preshear` function seems to have always used an invalid constructor
internally, and has been broken for a while.  Fixed the implementation and added a test.
