Sometimes we need to capture stack trace on one debugger and use it
later as a parent stack on another debugger (e.g. worker.postMessage).
This CL includes following addition to our protocol and v8-inspector.h:
- added Runtime.StackTraceId, this id represents stack trace captured
on debugger with given id,
- protocol client can fetch Runtime.StackTrace by
Runtime.StacKTraceId using Debugger.getStackTrace method,
- externalParent field is added to Debugger.paused event, it may
contain external parent stack trace,
- V8Inspector::storeCurrentStackTrace captures current stack trace
and returns V8StackTraceId for embedder this id can be used as
argument for V8Inspector::externalAsyncTaskStarted and
V8Inspector::externalAsyncTaskFinished method. Any async stack
trace captured between these calls will get passed external stack
trace as external parent. These methods are designed to be called
on different debuggers. If async task is scheduled and started on
one debugger user should continue to use asyncTask* API,
- Debugger.enable methods returns unique debuggerId.

Old instrumentation was designed to collect promise creation stack and
promise scheduled stack together. In DevTools for last 6 months we
show only creation stack for promises. We got strong support from users
for new model. Now we can drop support for scheduled stacks and
simplify implementation.
New promise instrumentation is straightforward:
- we send kDebugPromiseThen when promise is created by .then call,
- we send kDebugPromiseCatch when promise is created by .catch call,
- we send kDebugWillHandle before chained callback and kDebugDidHandle
after chained callback,
- and we send separate kDebugAsyncFunctionPromiseCreated for internal
promise inside async await function.
Advantages:
- we reduce amount of captured stacks (we do not capture stack for
promise that constructed not by .then or .catch),
- we can consider async task related to .then and .catch as one shot
since chained callback is executed once,
- on V8 side we can implement required instrumentation using only
promise hooks,
Disadvantage:
- see await-promise test, sometimes scheduled stack was useful since we
add catch handler in native code,
Implementation details:
- on kInit promise hook we need to figure out why promise was created.
We analyze builtin functions until first user defined function on
current stack. If there is kAsyncFunctionPromiseCreate function then
we send kDebugAsyncFunctionPromiseCreated event. If there is
kPromiseThen or kPromiseCatch then only if this function is bottom
builtin function we send corresponded event to inspector. We need it
because Promise.all internally calls .then and in this case we have
Promise.all and Promise.then on stack at the same time and we do not
need to report this internally created promise to inspector.

Use case: anonymous script with sourceMappingUrl. User can set
breakpoint in source with sourceUrl from sourceMap, we persist this
breakpoint in DevTools and on page reload breakpoint should be restored
correctly.
Debugger.setBreakpointByUrl method provides capabilities to set
provisional breakpoints and looks like best candidate for new "scriptHash"
argument.
I considered other options such as replacing scriptId with something
more persistent like "script-hash:script-with-this-hash-number" but it
looks more complicated and doesn't provide clear advantages.

console.context(name:string) method returns console instance, this console instance fully implements console interface (including fact that any method can be called without console as receiver).
Protocol.Runtime.consoleAPICalled notification contains additional context:string field:
- "anonymous#unique-id" for any method call on unnamed console context,
- "name#unique-id" for any method call on named console context.
console.count and console.timeEnd have context as a scope.
console.clear clear all messages regardless on what context instance it was called.
console calls is ~10% slower with this CL since we need to store and then fetch console_context_id and console_context_name from function object.
We recently (in April) made console calls twice faster so 10% doesn't sound critical and existing of console.log call in hot code is problem by itself.

In particular, local variables should be allocated on stack (in bytecode register), and stored/loaded to the generator object on generator suspend/resume.
The CL is based on @adamk's change to scoping/parsers (https://chromium-review.googlesource.com/c/498538/), I only made the debugger cope with this change.
I should note that the CL changes the scope type of suspended generators from ScopeType.Closure to ScopeType.Local. In the future we might want to introduce ScopeType.SuspendedGenerator to make the distinction explicit.
Some of the changes in the tests have been made because the debugger functions do not return scopes of closed generators anymore. Generators should be allowed to throw away their internal state when they finish.
