Martin Blicha 3599c8c6b9 SMTChecker: Fix generation of smtlib scripts

When both CHC and BMC engines are used, the type of state variable
changes when trusted mode for external calls is used. This is because in
CHC engine, trusted mode means we pack more information into the
symbolic state. In BMC this type is always simple.

However, if BMC is run after CHC, in the current code state variables
are reset (and their declaration dumped into SMT-LIB script) before BMC
resets the type of the state variable.

The proposed solution is to simply reset the variable type before the
first variable of this type is created.
