Since the same value is also returned in 'result' field it is still populated in accord with 'returnByValue' parameter. This behavior is consistent with 'evaluate'.

The spec says we have to insert some wrapper code with extra line breaks
in it, but this confuses users when they see stack traces as the line
numbers come from the code with the wrapper, instead of the original.
This CL sets line_offset on the script to indicate that line numbers
should be offset by the 2 extra line breaks when reading them out e.g.
for the purpose of stack traces.

Currently, the private name symbols are displayed in the block
scopes in DevTools, though these are just implementation details
of private fields. This patch hides them from the block scope
by marking variables with names starting with `#` as synthetic.
The private fields are still going to show up in the previews

This CL moves the code responsible for serializing a stack trace frame into
a string, out of messages.cc and into stack-frame-info.cc. Instead of
symbolizing the stack trace frame while serializing, the code is changed to
work on top of StackTraceFrame and StackFrameInfo objects.
The result is that the serialization code no longer cares when a stack trace
frame is symbolized. Symbolization could happen eagerly during capturing, or
lazily the first time any of StackFrameInfo fields are accessed.
Drive-by: Existing users of StackFrameBase::ToString are adapted to the
new SerializeStackTraceFrame API. This includes Isolate::PrintCurrentStackTrace,
which is changed to re-use the existing capturing and serializing mechanism.

The debugger should be notified whenever a new Module is created so it
displayed properly. Without this change, the Module is only displayed once,
regardless of the number of times it is referenced (by other Workers, say).
That is potentially reasonable behavior, but it doesn't match the way
JavaScript does it.
With this change, the debugger will display the sources like this:

Now that function counts are based on dedicated call counters instead

Prior to this CL, call counts at function scope were taken from the
FeedbackVector::invocation_count field. This had two major drawbacks:
1. for generator functions, these count the number of resumptions
instead of the number of calls; and 2. the invocation count is not
maintained in optimized code.
The solution implemented here is to add a dedicated call counter at
function scope which is incremented exactly once each time the
function is called.
A minor complication is that our coverage output format expects
function-scope counts in the dedicated CoverageFunction object, and
not as a CoverageBlock. Thus function-scope block counts are initially
marked with magic positions, and later recognized and rewritten during
processing.
This CL thus fixes reported generator function call counts and enables
optimizations in block coverage modes (more to come in a follow-up).
Drive-by: Don't report functions with empty source ranges.

The main change here is that in isolate-data.h, I'm switching from stateJSON to state.
This routine returns a CBOR encoded state cookie, which is also what we already
use in Chromium (blink).
In inspector-test.cc, I then put this byte vector into a V8 String,
and to make this roundtrip, change the extraction routine to get the
bytes. It's a little weird to store arbitrary bytes inside a v8 string,
but it appears to work fine because these bytes end up in the 8 bit portion,
much like isolatin characters would.

Patchset 2 was created by running clang-format. Patchset 3 then

... by skipping over them. Such variables appear in the case of direct
namespace exports and default exports. (Actually, the name used for
default exports used to be "*default*" which is not recognized as
synthetic, so I'm renaming it here to ".default").

This will allow the devtools UI to display private fields on the scope
panel.
Instead of extending GetInternalProperties, we expose a separate
GetPrivateFields method on the debug interface. This allows us to do
better type checking, for example, we can directly cast to a
v8::Private as this can only contain private fields.
This also allows us to have better constraints on the input type --
v8::Object, as opposed to a v8::Value.
The KeyAccumulator is extended to collect private names for the
PRIVATE_NAMES_ONLY PropertyFilter.

Do not leak handles to the outer scopes from inspector methods.
Add `SealHandleScope`s to the tests and the d8 binding, and
`HandleScope`s in the places in the inspector source where
handles are actually used.

New tests added for these calls:
* evaluateOnCallFrame
* setAsyncCallStackDepth
* setBreakpoint
* setVariableValue
For setAsyncCallStackDepth, this change updates the test to manufacture async callstacks in a different way so that there is more than one. The previous promise chain method was broken by f61facf.
