Rebase; Fix all LNT tests except llvm.org/PR26718

This is not yet a clean patch.

TODOs:

- Change analysis/transformation to work with exiting MemoryAccesses (instead of modifying their creation) in order to benefit from changes in http://reviews.llvm.org/D13611.
- Per-edge MemoryAccesses required for many tests cases to work properly. http://reviews.llvm.org/D15722 might be useful.
- Add systematic unit tests
