BlockCannotReturn exception is resumable but it shouldn't be

[adri09070]

BlockCannotReturn error has the "resumable" property so when this error happens, a debugger opens and the user can proceed the execution and ignore the error. However, doing so causes the image to crash: this is not good.

I think that this is misleading. If ignoring the error causes the image to crash, I think we shouldn't let the user proceed the execution. To do that, we should make this error not resumable
