removing dependencies on simplifier, support SMTLIB2 parametric algebraic datatypes.
This is a breaking change. It introduces two substantial changes:
1. The legacy simplifier is removed. It was obsoleted with the introduction of the rewriter facilities, but many dependencies made it a major change to remove the legacy simplifier. All uses of the legacy simplifier have now been replaced by corresponding calls to the rewriter. It means that some normalization may behave differently. At this point, Z3 passes regressions and passes performance tests without regressing.
2. Algebraic datatypes in the form of SMT-LIB2.6 are now supported. These generalize the datatypes supported so far as parametric datatype constructors may be applied to different arguments within a recursive definition.

[CMake] Move CMake files into their intended location so the
...
`contrib/cmake/bootstrap.py` script no longer needs to be executed.
The previous location of the CMake files was a compromise proposed
by @agurfinkel in #461 . While this has served us well (allowing progress
to be made) over time limitations of this approach have appeared.
The main problem is that doing many git operations (e.g. pull, rebase)
means the CMake files don't get updated unless the user remembers to
run the script. This can lead to broken and confusing build system
behaviour.
This commit only does the file moving and necessary changes to
`.gitignore`. Other changes will be done in subsequent commits.
