vm: never abort on caught syntax error
Keep track of C++ `TryCatch` state to avoid aborting when
an exception is thrown inside one, and re-throw in JS
to make sure the exception is being picked up a second time by
a second uncaught exception handler, if necessary.

Add a bit of a hack to `AppendExceptionLine` to avoid overriding
the line responsible for re-throwing the exception.
