a25a55e874 [wasm] Emit bytecode positions for --trace-turbo
This adds a decorator to add the wasm bytecode offset as origin
for graph nodes and emits a little table that maps lines in the
generated wasm assembly listing to the corresponding bytecode
offset.

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

9a43b37899 [objects] Deprecate GetIsolate/Heap behind a flag
Adds a new flag v8_deprecate_get_isolate that marks
HeapObject::GetIsolate/GetHeap, Handle<T>(T*) and handle<T>(T*) as
[[deprecated]]. Deprecation warnings are not converted to errors so an
entire build can be completed to collect all the warnings.

Also adds a new script tools/collect_deprecation_stats.sh which runs the
build (assuming the flag is set) and collects the number of uses of
deprecated functions. E.g. at the time of upload, we get:

Total deprecated calls: 2265
    515 GetHeap
    842 GetIsolate
    210 handle
    698 Handle

035dbdd93f PPC/s390: [sfi] Compress function arg counts to 16 bit
Port 53d4dfc377

Original Commit Message:

    Compress the parameter count (and function length) stored in
    SharedFunctionInfo to a uint16_t. This limits us to 2^16 - 1 parameters
    per function, minus one for the "don't adapt arguments" sentinel value,
    which is one fewer than Code::kMaxArguments was already. Anyway, 65534
    arguments should be enough for anyone!

    This drops SFI size by 4 bytes.

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.

which is one fewer than Code::kMaxArguments was already. Anyway, 65534
arguments should be enough for anyone!

This drops SFI size by 4 bytes.

b6c9086ca1 [inspector] reworked async stack instrumentation for async functions
New intstrumentation consists of:
- kAsyncFunctionSuspended when async function is suspended on await
  (called on each await),
- kAsyncFunctionFinished when async function is finished.

Old instrumentation was based on reusing async function promise.
Using this promise produces couple side effects:
- for any promise instrumentation we first need to check if it is
  special case for async function promise or not - it requires
  expensive reading from promise object.
- we capture stack for async functions even if it does not contain
  awaits.
- we do not properly cancel async task created for async function.

New intsrumntation resolved all these problems as well as provide
clear mapping between async task and generator which we can use later
to fetch scope information for async functions on pause.

6d87d95785 [inspector] use interrupt for pause only as last resort
With this CL we use interrupt for pause in two cases:
- when we process Debugger.pause on interruption,
- when we would like to break as soon as possible after OOM.
In all other cases, e.g. for async step into we use break
on function call by calling StepIn debugger action.

In mentioned cases we should not actually use interrupt as well:
- Debugger.pause in this case scheduled using interrupt and we
  may just break right now without requesting another interrupt,
  unfortunately blink side is not ready,
- we should use more reliable way to break right after near OOM
  callback, otherwise we can get this callback, increase limit,
  request break on next interrupt, before interrupt get another
  huge memory allocation and crash.

There are couple advantages:
- we get much better break locations for async stepping
  (see inspector tests expectations),
- we can remove DEBUG_BREAK interruption
  (it should speedup blackboxing with async tasks, see
  removed todo in debug.cc for details)
- it is required preparation step for async step out,
  (see https://chromium-review.googlesource.com/c/v8/v8/+/1054618)
