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.

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.

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,

This extends the ScriptCompiler::CompileModule function with a
CompileOptions argument. Accepted values are kNoCompileOptions (in
which case, behavior remains unmodified) and kConsumeCodeCache. If the
latter is passed, we try to fetch the given module from the code

Since it is possible to compile the same source code as both a script

new is_module bit is added to the SerializedCodeData header to
disambiguate between the two cases.

see crbug.com/841460 , we recently hit some build issues when using
Goma + jumbo builds because of a conflict on the definition of CONST,
v8 defines it in globals.h and including windows.h also defines it. It
should be possible to fix this by adding a bunch of #undef CONST but it
seems a little bit hacky and might not always work (this could only fix
the problem temporary if the jumbo merge limit changes and cause some
include files to get included in a different order).
Renaming the v8 definition of CONST to kConst, this follows the
style guide guidelines: "there is no reason to change old code to use
constant-style names, unless the old names are actually causing a
compile-time problem"
(https://google.github.io/styleguide/cppguide.html#Enumerator_Names)
I also had to turn the PropertyConstness enum into an enum class to
avoid some conflicts (both PropertyConstness and VariableMode define
kConst).

- Resume copies only the registers from the generator, the arguments

The current profiling mode (called kLeafNodeLineNumbers in this CL)
produces a tree, with each node representing a stack frame that is seen
in one or more samples taken during profiling. These nodes refer to a
particular function in a stack trace, but not to a particular line or
callsite within that function.
This CL adds a new more (called kCallerLineNumbers) which produces a
different profile tree, where each stack trace seen during profiling,
including the line number, has a unique path in the tree.
The profile tree was previously keyed on CodeEntry*. Now it is keyed on
the pair of CodeEntry* and line_number, meaning it has distinct nodes
for those combinations which exist, and each distinct stack trace that
was sampled is represented in the tree.
For optimized code where we have inline frames, there are no line
numbers for the inline frames in the stack trace, causing duplicate
branches in the tree with kNoLineNumberInfo as the reported line number.
This will be addressed in follow-ups.

This map is often quite small and holds small items (ints) so wastes
quite a bit of overhead in the backing tree representation.
This CL changes the std::map to a sorted vector of pairs. This reduces
the size significantly (2.13 MiB -> 598 KiB on the node server example).

ToDirectStringAssembler::PointerToData returns a raw pointer, which
is invalidated when GC moves the original string and hence must not
be accessed after any allocations. This fixes the bug introduced in

When processing imports of an instance, we were storing pointers to
exported (and re-imported) wasm functions in the code table of the
importing module. This is dangerous since imports are instance specific.
Avoid ever storing call targets for imports in the NativeModule.
Instead, read the call targets from the imports table of the instance.

Currently ProfilerListener holds all the CodeEntries it ever
created during the profiling session. It is not capable of removing
entries corresponding to the code objects discarded by GC as there's
no such code event.
However it is sometimes possible to tell if a code object was GCed.
Hook up to the CodeMap code entry removal and if the entry has never
been hit by a sample we can safely delete it.
As a bonus the CodeEntryInfo size has been reduced on x64, which also
saves 8 x <number of code entries> bytes.

Array.indexOf accepts an optional fromIndex argument. When non-negative,
this argument restricts the searched indices to those starting at
fromIndex:
[1, 2, 1].indexOf(1,1) == 2
When negative, it is meant to be added to the array length to provide
such initial index for the search:
[1, 2, 1].indexOf(1, -2) == 2
This transformation has been done by the non-optimised builtin but not
by the reducer. The CL adds this construction to the reducer.

ArrayBuffer memory allocated off-heap was previously tracked by a test-
only retained_size() field on each LocalArrayBufferTracker.
Changes in off-heap ArrayBuffer memory usage are now reported to the
Space with which the ArrayBuffer is associated, so that the value is
cheaply available to include in e.g. GC limit calculations, via a new
getter, ExternalBackingStoreBytes().
Changes to external ArrayBuffer backing-store allocations are tracked in
an AtomicNumber associated with each Space, to allow for ArrayBuffers
being concurrently moved or freed from multiple Pages in the same Space
during sweeps & compactions.
