We cannot use the generic reentrancy guard in the LSI code, so we have to manually prevent endless reentrancy here. The problematic lsi_execute_script() function has already a way to detect whether too many instructions have been executed - we just have to slightly change the logic here that it also takes into account if the function has been called too often in a reentrant way. The code in fuzz-lsi53c895a-test.c has been taken from an earlier patch by Mauro Matteo Cascella.
