51a947b73d 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.

cfd0486582 Catch exceptions by const-reference 
Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.
