ThrowScopes should not be able to clear termination exceptions
https://bugs.webkit.org/show_bug.cgi?id=305496
rdar://168161400
Reviewed by Yusuke Suzuki.
Right now when folks call clearException on a ThrowScope they often end
up unintentionally clearing termination exceptions. This is a bit of a
footgun.
With this change it's now only possible to tryClearException, which
fails when there's a termination exception pending. Long term, the goal
is to have all "interior" code use ThrowScopes as they have to support
propagating termination exceptions. I fixed a few places in this patch
such as IteratorOperations and will fix the remaining ones when renaming
CatchScope in a follow up change.
No new tests, no behavior change.
