Seth Brenith 2048ee8b1d Redirect BytecodeArray pointers on stack when clearing DebugInfo
When clearing a DebugInfo, we need to check whether that function is
currently executing and, if so, update the on-stack BytecodeArray
pointer to refer to the original BytecodeArray. Otherwise, the original
BytecodeArray might get flushed, which can cause problems when
attempting to resume execution of the function.
