a11b0d962d [inspector] improve this value for arrow function in scopes
Currently we incorrectly show global object as arrow function receiver.
With this CL:
- if this is used inside of function we show correct this value,
- if this is unused and V8 optimizes it out - we show undefined.

Second is known issue which we should address separately.

8319882972 [inspector] provisional breakpoints for anonymous script
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.

335c8ad009 [type-profile] Incorporate into inspector protocol.
JavaScript is a dynamically typed language. But most code is 
written with fixed types in mind. When debugging JavaScript, 
it is helpful to know the types of variables and parameters 
at runtime. It is often hard to infer types for complex code. 
Type profiling provides this information at runtime.

Node.js uses the inspector protocol. This CL allows Node.js users 
to access and analyse type profile for via Node modules or the
in-procress api. Type Profile helps developers to analyze 
their code for correctness and performance.  

Design doc: https://docs.google.com/a/google.com/document/d/1O1uepXZXBI6IwiawTrYC3ohhiNgzkyTdjn3R8ysbYgk/edit?usp=sharing

Add `takeTypeProfile` to the inspector protocol. It returns a list
of TypeProfileForScripts, which in turn contains the type profile for
each function. We can use TypeProfile data to annotate JavaScript code. 

Sample script with data from TypeProfile:
function f(/*Object, number, undefined*/a, 
           /*Array, number, null*/b, 
           /*boolean, Object, symbol*/c) {
  return 'bye';
/*string*/};
f({}, [], true);
f(3, 2.3, {a: 42});
f(undefined, null, Symbol('hello'));/*string*/

fe598532ec Pass Isolate pointer to String::Utf8Value/Value constructors
As part of J2V8 development (https://github.com/eclipsesource/J2V8),
we realized that we had a subtle bug in how Isolate scope was created
and it's lifetime managed, see:
https://github.com/eclipsesource/J2V8/issues/313.

Mentioned above bug was fixed, however, what we also noticed is that
V8 API has been constantly and slowly moving to such an API, in which
one has to pass Isolate explicitly to methods and/or constructors. We
found two more places that might have been overlooked. This contribution
adds passing of Isolate pointer explicitly to constructors of
String::Utf8Value and String::Value classes.

8aed7767d6 [inspector] send internal properties first, remove unnecessary props
Currently, injected script source adds natural object properties before
internal properties. This can result in important ones such as
"[[PrimitiveValue]]" being left out. This CL
- makes sure internal properties are always added to preview
- removes unused "[[Iterator*]]" properties from preview
- boxed strings (e.g. new String("foo")) will not send unnecessary
properties 0:"f", 1:"o", 2:"o" if the [[PrimitiveValue]] is sent.

Add "detailed" flag to Profiler.startPreciseCoverage to specify
granularity (block coverage vs function coverage).

The default value is currently set to FLAG_block_coverage, which
is currently true. This is so that the V8 roll does not break
LayoutTests. I'll set it to false once I made changes to Blink.

With awaitPromise flag Runtime.evaluate awaits
Promise.resolve(<expression result>).
This also allows to await for any non-Promise value, similar to await

f984eb1bbb [test] Rebaseline inspector test.
This changes the baseline of an inspector test setting breakpoints
within an asm.js module while the module is being executed. With the
validator it is not supported to switch from active WebAssembly code
back to debuggable interpreter code. Hence some previously expected
breakpoints no longer fire, the behavior is consistent across all
configurations now though.
