This is a reland of 3dd5661204
The reland introduces a new flag "--experimental-stack-trace-frames".
The flag is disabled by default, but enabled for relevant tests.
The flag stays disabled by default until API frames are eagerly
symbolized to prevent leaks in blink web tests.
Original change's description:
> [stack-trace] Include API functions in Error.stack stack trace

> with the C++ FunctionTemplate API. For example, "print" in d8.
>
> Two changes are necessary:
> - HandleApiCall and friends need to go through an BUILTIN_EXIT frame

> - Turbofan doesn't go through HandleApiCall, but instead uses an

> frame state is needed to include these frames in the stack trace.
>
> Note: This CL only includes these frames in Error.stack,

Inputs to JSON can be two-byte because payload strings can contain two-byte
characters, without actually having any one-byte property key. Rather than
eagerly converting the string to one-byte, we can perform a string-table lookup
with a two-byte string key; only converting the result to one-byte if it's a
new key.
This speeds up json parsing of two-byte json from the Youtube benchmark by 20%.

Factory::NewStackFrameInfo was leaving fields with the default

Our heap verifier dutifully found and reported the discrepancy. This CL
initializes all fields of the struct to values compatible with the Torque

Macros are now inaccessible from CSA except if their declaration is
marked with the "export" keyword. The implicit field accessors for class
fields are always exported.
In this CL, unwarranted access from CSA is prevented by appending a
pseudo-random suffix to non-exported names. This is to be replaced by
something more principled, namely by not including these macros at all in
the headers included from CSA.

Previously, compiling with perfetto would add 2.3 MiB to the d8 release
binary. With this change it's 472 KiB.
This is because trace:lite pulls in many more compiled proto classes
than we need, e.g. a bunch of stuff under ftrace/ which is only used
on Android.
Chrome uses a 'mirror proto' ChromeTrackPacket to only provide
compiled protos for the types of packets it will actually see, which on
non-android devices does not include anything under ftrace/.
We use the same trick here in the JSON consumer.

The read_only_object_cache call cannot return a vector when it is backed
by the embedded heap, so this adds a few methods to abstract this away.
ExtendReadOnlyObjectCache will eventually have a check to reject adding
objects to the embedded read-only object cache.
Prior to this change the read-only object cache would only be extended
conditionally if needed. Since it started out empty it was always
extended, so this removes this logic.

ASAN on Windows uses exceptions to manage its shadow memory. However,
this behavior can conflict with WebAssembly trap handler, because
WebAssembly trap handler are executed before the ASAN exception handler.
For some WebAssembly instructions we do not generate assembly code but
call to C functions instead. Since these functions are very simple, we
do not want to reset the thread-in-wasm flag before calling them.
However, when these functions trigger the ASAN exceptions, the
thread-in-wasm flag gets out-of-sync. This happened for the
memory_fill_wrapper function. Originally we thought that it's sufficient
to just mark the function with DISABLE_ASAN. However, this is not enough
because clang compiles the function to use memset, and memset gets
replaced by ASAN with asan_memset.
Therefore I decided now that just for sanitizer builds on Windows, we
reset the thread-in-wasm flag in memory_fill_wrapper. This is not ideal
because it's test-specific code within production code. However, the
alternatives also don't sound convincing.
Alternatives would be:
* Resetting the thread-in-wasm flag whenever we call a c-function
- This would be unnecessary performance overhead for production code
just to make a test work.
* Configure ASAN to not change memset.
- This would weaken ASAN also for other cases.
* Disable ASAN for trap handlers, or trap handlers in ASAN builds.
- This would reduce test coverage.

The invariant is that Map::bit_field2 shouldn't change, and the
IsInRetainedMapListBit apparently changes when the map is held
weakly from optimized code. This causes TurboFan compilations to
change the Map::Hash() result, which in turn causes lookups on
the normalized map cache to miss (and maybe other bad consequences).
With this change we swap Map::IsInRetainedMapListBit (previously in
bit_field2) and Map::HasHiddenPrototypeBit (previously in bit_field3)
to address this problem.

If speculation is disallowed, this change lets us still do the
optimization if (a) the maps were already reliable or
(b) we are able to take stability dependencies.

after the snapshot was created ever since the CallApiCallback stub was
turned into a builtin.

deopt-unlinked.js: bytecode flushing destroys the information that
%GetDeoptCount relies on, so turn that off for this test.
cleanupsome-after-unregister.js: the function-local object {o} is
assumed to be alive throughout the function, so make sure its live
range (from the optimizing compiler's view) extends that far.
Drive-by cleanup: drop some unnecessary casting boilerplate from
Genesis::InitializeGlobal_harmony_intl_date_format_range().
