[JSC] Handle termination exception after draining microtasks in jsc shell
https://bugs.webkit.org/show_bug.cgi?id=302304
rdar://163999397
Reviewed by Keith Miller.
Throwing a termination exception in a microtask causes the draining to stop,
but does not forbid future execution, and also proceeds to do deferred work.
Doing deferred work with a termination exception pending on the VM can trigger
asserts.
This PR only continues further execution in the jsc shell after draining
microtask queue if a termination exception was not thrown.
Test: JSTests/stress/jsc-termination-in-microtask.js
* JSTests/stress/jsc-termination-in-microtask.js: Added.
