Krzysztof Parzyszek cfb0063c60 [Hexagon] Avoid infinite loops in HexagonLoopIdiomRecognition 
- Avoid explosive growth of the simplification queue by not queuing
  expressions that are alredy in it.
- Add an iteration counter and abort after a sufficiently large number
  of iterations (assuming that it's a symptom of an infinite loop).

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
