Nikolaj Bjorner e0ac5bd585 Merge pull request #1013 from NikolajBjorner/master 
Integrate new LRA solver capabilities by Lev Nachmanson. 

The LRA solver relies on a portfolio of Simplex implementations.
For large problems it resorts to revised Simplex with different search options. It uses doubles for large systems. For smaller problems it uses a Dual Simplex tableau representation that outperforms the scalable solver when many small calls are used. It uses infinite precision rationals by default. 
The theory_lra class provides the interface to the scalable Simplex solver.

This breaks the `clean` rule when using Ninja as the CMake
generator. Unfortunately this means `clean` doesn't try to
remove the generated documentation anymore when using Ninja.
