When trying to print the scope information for the class fields
initializer function, the debugger asks the parser to parse the class
literal as a function literal (to get the scope info) ... which
doesn't quite work.
Instead of adding support for parsing the class literal, we just short
cicruit this parsing step by just returning an empty context.
This works fine because initializer function doesn't have any
variables in it's local scope.
The one caveat is that the objects in the scope above this function
(like the global) are now missing. This trade off is possibly fine
for now, as adding parsing support for class literal to only produce
would be a lot of code for not enough use.
As a follow up to this change, the devtools UI needs to be updated to
handle this empty context cleanly. Currently, it doesn't show the
`this` object if no context exists even if the `this` object is
correctly passed to the UI from the backend.

This change introduces new intrinsics used to desugar async functions
in the Parser and the BytecodeGenerator, namely we introduce a new
%_AsyncFunctionEnter intrinsic that constructs the generator object
for the async function (and in the future will also create the outer
promise for the async function). This generator object is internal
and never escapes to user code, plus since async functions don't have
a "prototype" property, we can just a single map here instead of tracking
the prototype/initial_map on every async function. This saves one word
per async function plus one initial_map per async function that was
invoked at least once.
We also introduce two new intrinsics %_AsyncFunctionReject, which
rejects the outer promise with the caught exception, and another
%_AsyncFunctionResolve, which resolves the outer promise with the
right hand side of the `return` statement. These functions also perform
the DevTools part of the job (aka popping from the promise stack and
sending the debug event). This allows us to get rid of the implicit
try-finally from async functions completely; because the finally
block only called to the %AsyncFunctionPromiseRelease builtin, which
was used to inform DevTools.
In essence we now turn an async function like
```js
async function f(x) { return await bar(x); }
```
into something like this (in Parser and BytecodeGenerator respectively):
```
function f(x) {
.generator_object = %_AsyncFunctionEnter(.closure, this);
.promise = %AsyncFunctionCreatePromise();
try {
.tmp = await bar(x);
return %_AsyncFunctionResolve(.promise, .tmp);
} catch (e) {
return %_AsyncFunctionReject(.promise, e);
}
}
```
Overall the bytecode for async functions gets significantly shorter
already (and will get even shorter once we put the outer promise into
the async function generator object). For example the bytecode for a
simple async function
```js
async function f(x) { return await x; }
```
goes from 175 bytes to 110 bytes (a ~38% reduction in size), which
is in particular due to the simplification around the try-finally
removal.
Overall this seems to improve the doxbee-async-es2017-native test by
around 2-3%. On the test case mentioned in v8:8276 we go from
1124ms to 441ms, which corresponds to a 60% reduction in total
execution time!

DebugEvaluate contains code since 2009 that bypasses JSGlobalProxy and

This behavior may be dangerous:
- JSGlobalObject does not perform security checks,
- some parts of V8 code do not ready for JSGlobalObject, e.g.,
SetHashAndUpdateProperties function will crash on DCHECK if we will
try to store JSGlobalObject to map.
At the same time it looks like there is no any valid use case for it.

Liveedit step-by-step:
1. calculate diff between old source and new source,
2. map function literals from old source to new source,
3. create new script for new_source,
4. mark literals with changed code as changed, all others as unchanged,
5. check that for changed literals there are no:

- non droppable frames (e.g. running generator) above them on stack.
6. mark the bottom most frame with changed function as scheduled for
restart if any.
7. for unchanged functions:
- deoptimize,
- remove from cache,
- update source positions,
- move to new script,
- reset feedback information and preparsed scope information if any,
- replace any sfi in constant pool with changed one if any.
8. for changed functions:
