Change how 64 bit builds are detected.
...
Instead of doing this at configure time, we look at the actual
compile time status. This also avoids hardcoding checks based on
what CPU architecture is present, which doesn't work when Z3 is
being built on non-x86_64 platforms.

Fix incorrect (off by one) bound check. Also assert that we don't
...
increment ``m_num_segments`` beyond the maximum value
(``c_max_segments``).
This is related to #436 .
When doing an AddressSanitized build and running the ``c_example``
it looks like Z3 tries to create too many segments and index out of
bounds. Fixing the checks here causes them to fail which should help
us narrow down the problem.
