Fix recursive calling of QScriptProgram
The first time a QScriptProgram is evaluated, it gets compiled and
then executed. If the execution would somehow trigger another
evaluation of the script program, it would run into the compile
stage again (even though it already was compiled), and then trigger
and assertion in debug mode (or leak memory in release builds).
Backport of 08d9ef715265d33f4cf04693b0787fd75994dc42 from Qt 5.
