8205786a4b [inspector] decouple debugger delegate and async stacks delegate
Currently we enable instrumentation if debugger is active. With this
approach we can not:
- capture async stack when debugger is disabled,
- avoid async instrumentation overhead when debugger is enabled and
  async stacks are disabled.

91bab5588c [array] Use random middle element to determine pivot during sorting
This CL adds a "random state" to the Smi Root list and implements a
basic Linear congruential pseudo random number generator in Torque.

The RNG is used to determine the pivot element for sorting. This will
prevent the worst cases for certain data layouts.

Drive-by-fix: Make sorting of ranges and execution pauses for profviz
deterministic by adding a secondary sorting criteria.

ceb9c8127f [sfi] Remove SFI function literal id field
SharedFunctionInfos store their original function literal's id. This is
also their index in the Script's SFI list.

Since the function literal id is only needed for lazy compilation and live
edit, we can calculate it on-the-fly by linear search in the Script SFI list,
and save a field on the SFI.

If this regresses compile performance, we could alternatively store the
function literal id on the preparsed scope data as future work.

d123f30b6d [ptr-compr] Support 31-bit Smis in lower half-word on 64-bit architectures.
This CL introduces a new gn argument: v8_enable_pointer_compression which is
false by default. All the changes done in this CL are made under this flag.

Upper half-word of a Smi word must be properly sign-extended according to the
sign of the lower-half containing the actual Smi value.

4ce2adc326 [explicit isolates] Eliminate GetIsolate from transitions.cc
Removes all explicit calls to GetIsolate() in transitions.cc by passing
it through calling functions and implicit calls via the single argument
Handle constructor and handle function.

Unfortunately in the interests of making these changes vaguely
manageable, I've also pushed some new GetIsolates down into
objects-debug.cc, objects-printer.cc and objects.cc.

5eaa03b2d3 [api] Add AtomicsWaitCallback for diagnostics
Add an inspection callback for embedders that allows tracking
of `Atomics.wait()` calls in order to enable diagnostic tooling
around it, as well as providing a way to break out of an
`Atomics.wait()` call without having to fully terminate execution.

The motivation here is that this allows embedders to perform
somewhat customizable deadlock detection.

b1583b6cd3 [wasm] Load {CEntryStub} from the instance object.
This avoids embedding the {CEntryStub} into generated {WasmCode} and
instead loads it from the instance object. It is another step towards
making the generated code independent of the Isolate.

18d816e96e [wasm] Clean up fields and methods in NativeModule
1) The code table never grows, so store it in a heap-allocated byte
   array instead of an std::vector.
2) Rename {functions_count} to {num_functions} for consistency with
   {num_imported_functions} and occurences in other data structures.

c96ac82c50 [wasm] Make stack check independent of the Isolate.
This makes stack checks in WasmCode independent of the underlying
Isolate by loading the limit address from the WasmInstanceObject instead
of embedding it into the instruction stream. It hence removes the last
use of the Isolate field from WasmGraphBuilder.

Additionally this introduces the notion of a "runtime stub" which
represents stub code global to the NativeModule that can be directly
called from each WasmCode in the same module. These stubs can act as
trampolines via which Isolate-independent WasmCode can enter other V8
builtins or runtime functions that remain Isolate-dependent. They will
eventually replace the current "trampoline" in a NativeModule.

df1676e616 [array] Implement Array.p.sort in Torque
This CL implements a generic baseline version and 3 fastpaths, for
various elements kinds, of Array.p.sort in Torque. Details can be found
in the Design Doc: https://goo.gl/Ge321G.

Performance impact on micro benchmarks depends on the element kind
and whether the user provides a comparison function.
For HoleySmi/HoleyElement we have a speedup between 1.5-1.8 across
the board. For Dictionary we are slower in all micro benchmarks (0.7).
For PackedSmi it depends on the call site and whether or not a
comparison function is used.

Detailed numbers: https://goo.gl/mTyPSb

49c4ac7753 [inspector] added Runtime.installBinding method
A lot of different clients use console.debug as a message channel from
page to protocol client. console.debug is a little slow and not
designed for this use case.

This CL introduces new method: Runtime.installBinding. This method
installs binding function by given name on global object on each
inspected context including any context created later.
Binding function takes exactly one string argument. Each time when
binding function is called, Runtime.bindingCalled notification is
triggered and includes passed payload.

Binding function survives page reload and reinstalled right after
console object is setup. So installed binding can be used inside
script added by Page.addScriptToEvaluateOnNewDocument so client may do
something like:
Runtime.installBinding({name: 'send'});
Page.addScriptToEvaluateOnNewDocument({source: 'console.debug = send'});
.. navigate page ..

In microbenchmark this function is ~4.6 times faster then
console.debug.
