Original issue's description:
> Array length reduction should throw in strict mode if it can't delete an element.
>
> When accessor getter callback is called the v8::PropertyCallbackInfo::ShouldThrowOnError() is always false, since according to ES6 there's no difference between strict and non-strict property loads.

>
> Interceptors follow same idea: for getter, enumerator and query callbacks the v8::PropertyCallbackInfo::ShouldThrowOnError() is always false, and for setter and deleter callback the v8::PropertyCallbackInfo::ShouldThrowOnError() returns true in strict context.

> Refactor object/class literal property name parsing
>
> This patch arranges that property names are parsed in a single pass,
> reporting the name as well as the type of the property, instead of
> parsing qualifiers like 'static' or 'get' initially as names and then
> re-parsing. This change is easier to reason about, very slightly (4%)
> faster in some cases (although slower in other, less common ones, though
> this slowdown will be fixed in an upcoming patch), and is a prerequisite
> for separating the parsing of object and class literal properties, which
> will become increasingly important as ECMAScript adds more class features.

- we should always set creation async stack if it's available regardless existing of current parent async stack,
- we should cleanup parent link iff there is no creation and schedule async stack for parent.

Let's consider example: Promise.resolve().then(x => x).then(x => x), there is three promises which will call following instrumentation:
1) created #1 (Promise.resolve()) - collected stack #1
2) scheduled #1 - collected stack v8#2
3) created v8#2 with #1 as parent (first .then) - collected stack v8#3
4) created v8#3 with v8#2 as parent (first .then) - collected stack v8#4
5) started v8#2 - use stack v8#2 as scheduled
6) scheduled v8#2 - collected stack v8#6
7) finished v8#2
8) started v8#3 - use stack v8#6 as scheduled
9) scheduled v8#3 - collected stack v8#7
10) finished v8#3

If we collect stacks between step 4 and 5, it's possible to collect scheduled stack v8#2 but still have creation stack for v8#2 - stack v8#3 - so we always need to add creation event if scheduled is collected.

If we collect stacks between created and scheduled we should not remove parent link even if parent was not scheduled yet.

Original issue's description:
> [turbofan] Add alignment parameter to StackSlot operator
>
> If alignment parameter is set, the memory returned by the
> StackSlot operator will be aligned according to the parameter.
>
> The implementation goes like this. If alignment parameter is set
> we allocate a bit more memory than actually needed and so we
> can move the beginning of the StackSlot in order to have it aligned.
