e423f00403 [api] Add a way to specify the max heap size in ResourceConstraints
The new API function is called ConfigureDefaultsFromHeapSize and
accepts two parameters: the initial and the maximum heap size.
Based on the given limits the function computes the default size
for the young and the old generation.

The patch also cleans up the existing functions to make them
consistent in terms of units and heap structure.

cbf72529da [api,heap] Allow decrementing allocated embedder size
Allow the embedder to decrement its allocated bytes count:
- The decrement will be applied to the used bytes value.
- The decrement is ignored for the total allocated bytes.

d365f62ec1 [tracing] Add a way to test perfetto traces.
Add a new abstract class TraceEventListener which is just an interface
for consuming trace events. This separates the V8-specific stuff that
an actual perfetto consumer needs to do e.g. handling the has_more flag
and signalling back to the controller with a semaphore.

This is a change from the previous plan of making the PerfettoConsumer
class sub-classable to implement custom consumption of trace events.
This will be difficult when the consumer is created outside of the
PerfettoTracingController as we can't hook up the
consumer_finished_semaphore_ that belongs to the controller.

Now the PerfettoTracingController is responsible for the Consumer life-
cycle and hides it entirely from callers. We add the
AddTraceEventListener() method to allow callers to register a listener
either for testing or a JSON listener for real tracing.

This lets us write tests that can store all the trace events in memory
without first converting them to JSON, letting us write test more
easily. There's an example test add to test-tracing - more tests using
this style will follow.

99a927c692 [api] Remove obsolete FunctionTemplate::SetHiddenPrototype().
The `FunctionTemplate::SetHiddenPrototype()` API was deprecated
beginning of the year and all uses in Node.js and Chrome have been
removed appropriately. This removes the implementation of the method
and the bit in the `FunctionTemplateInfo`, but retains the bit in
the Map for now. That will be cleaned up as a second step later.

880c3202e0 Reland "[heap] Add global memory controller"
Provide a global memory controller used to compute limits for combined
on-heap and embedder memory. The global controller uses the same
mechanism (gc speed, mutator speed) and growing factors as the regular
on-heap controller.

Rely on V8's mechanisms for configured state that stops shrinking the
limit.

Reland:
- API fixes with overrides and default versions.
- Fix of depending on uninitialized values when using the old API.
- GCTracer: Fixed issue in speed computation.
- GCTracer: Added unittests.

This reverts commit 5e043f2773.

2021d4ef2c [DevTools] Switch inspector-test.cc to use the CBOR encoded inspector state.
The main change here is that in isolate-data.h, I'm switching from stateJSON to state.
This routine returns a CBOR encoded state cookie, which is also what we already
use in Chromium (blink).

In inspector-test.cc, I then put this byte vector into a V8 String,
and to make this roundtrip, change the extraction routine to get the
bytes. It's a little weird to store arbitrary bytes inside a v8 string,
but it appears to work fine because these bytes end up in the 8 bit portion,
much like isolatin characters would.

7ebcb5a153 [stack-trace] Add 'IsUserJavaScript' flag to stack frame API
This CL extends the stack frame API to include a flag to distinguish
between user and V8 builtin frames. The intention is to extend the API in
a later CL, so stack traces include builtin frames.
This flag gives embedders more control what to do with builtin frames.

9d7c1947f5 [DevTools] Add V8InspectorSession::state(), which returns binary (CBOR).
Keep the existing method for compatibility, by converting
to json from CBOR using the inspector_protocol_encoding library,
via a v8 specific interface library that directs routines for
converting between strings and doubles to v8's implementations.

This change also brings in the encoding.h / encoding.cc files from the
upstream inspector_protocol project. The only modification here
are the header guards, and the namespace. I will fix roll.py to
make it so that we pick up future changes.

third_party/inspector_protocol/BUILD.gn is specific to v8, by necessity.
third_party/inspector_protocol/.clang-format is a copy of the upstream
file. If we don't put this, we'll find ourselves auto-formatting the roll,
which is annoying.

This is a reland of
https://chromium-review.googlesource.com/c/v8/v8/+/1590627 with the
only modification in the DEPS file; this time I'm including
third_party/inspector_protocol/encoding/encoding{.h,cc} in addition to
the relative include there. Not sure why this is needed but I'm hoping
it gets me past the presubmit which may resolve the include path
relative to the V8 base (the ../../third_party is needed for when V8 is
embedded into Chromium).

8f4063c6ea [tracing] Implement the default TracingController with Perfetto
Based on Primiano's prototype:
https://chromium-review.googlesource.com/c/v8/v8/+/1290549

This is still behind a build flag. I'll add functionality incrementally
rather than land everything in one giant CL.

This CL sets up the basic classes that will be used for the Perfetto
implementation, e.g. the producer, consumer, controller and task runner.

This implementation produces a binary proto file in the current
directory named v8_trace.proto. It doesn't yet produce JSON output,
that is coming in a following CL.

Currently the old tracing and perfetto tracing are both run alongside
each other if the build flag is enabled.

381a7f9e76 [Profiler] Ensure ticks in frameless bytecode handlers are interpreted frames.
On Arm/64 the last return address is stored in a link register instead of
being pushed to the top-of-stack like on x64/ia32. Extend the support in the
tick sampler to check for samples in a frameless bytecode handler with support
for checking the link register if it exists instead of top-of-stack. In addition,
make the x64/ia32 check more robust by ensuring we only apply the change if the
pc is a bytecode handler and the top frame isn't a bytecode handler (stub) frame.

97562879b1 Fix build error on ARM64/Windows
In file include/v8config.h we define:

ifdef V8_OS_WIN
...
if defined(_M_X64) || defined(__x86_64__)
  define V8_OS_WIN_X64 true
endif

and V8_OS_WIN_X64 is supposed to be defined when targeting X64 on Windows only.
But this is wrong because V8_OS_WIN_X64 gets defined also on an ARM64 builds
when the host machine is X64. It should instead be:

ifdef V8_OS_WIN
...
if defined(V8_TARGET_ARCH_X64)
  define V8_OS_WIN_X64 true
endif
