b411a66486 [build] Assert that webassembly is disabled on lite mode
This avoids having to check both flags in two places, and prevents
people from trying to enable WebAssembly in lite mode (which would
currently build, but you still would not get Wasm support).

The downside is that the default value shown by `gn args --list` now
sais `""` instead of `true`.

ca89bf259f [no-wasm] Exclude asm->wasm translation code

In order to skip specific unit tests in that configuration, we move the

v8.gni, such that it is available in all gn files.

v8_base_without_compiler to cppgc_base, which breaks build with

5f6aa2e5bf [heap] Add object start bitmap for conservative stack scanning
With conservative stack scanning enabled, a snapshot of the call stack
upon entry to GC will be used to determine part of the root-set. When
the collector walks the stack, it looks at each value and determines
whether it could be a potential on-heap object pointer. However, unlike
with Handles, these on-stack pointers aren't guaranteed to point to the
start of the object: the compiler may decide hide these pointers, and
create interior pointers in C++ frames which the GC doesn't know about.

The solution to this is to include an object start bitmap in the header
of each page. Each bit in the bitmap represents a word in the page
payload which is set when an object is allocated. This means that when
the collector finds an arbitrary potential pointer into the page, it can
walk backwards through the bitmap until it finds the relevant object's
base pointer. To prevent the bitmap becoming stale after compaction, it
is rebuilt during object sweeping.

This is experimental, and currently only works with inline allocation
disabled, and single generational collection.

0056effb20 tracing: Enable using Perfetto client library from Chromium
We are currently porting Chromium over to use the Perfetto client
library for tracing[1]. When this mode is enabled, V8 should also use
the Perfetto library built by Chromium instead of building an
indepedendent copy. This patch enables that behavior, gated by the
|use_perfetto_client_library| flag set by Chromium.

We also roll Perfetto to the latest version, add a couple of missing
dependencies on v8_tracing and add a missing tracing category group.

9dbab9bbdb [tracing] Migrate tracing to Perfetto track events
This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT
macros) with the track event base implementation from Perfetto. The
advantages of doing this are:

1) This allows us to remove most tracing-related backend code from V8.

2) V8 can start writing strongly typed trace event arguments, which
   are more compact, easier to process and more extensible than legacy
   JSON-based trace arguments.

For the time being, we still support the old trace macros when V8 is
embedded into Chrome and other embedders.

03fc414908 Add initial support for Wasm debugging with LLDB: implements a GDB-remote stub
This is the first piece of the wasm debugging prototype (besides the changes to
add/remove breakpoints in WasmModuleObject made with
e699f39cae).

This changelist adds the infrastructure for a GDB-remote stub that will be used
to manage debugging sessions via the gdb-remote protocol.
It enables the creation and termination of debugging sessions over TCP
connections that are managed in a separate thread.
The logic to actually send, receive and decode GDB-remote packets will be part
of a future changelist.

Build with: v8_enable_wasm_gdb_remote_debugging = true
Run with:
  --wasm-gdb-remote                  Enables Wasm debugging with LLDB
                                     (default: false)
  --wasm-gdb-remote-port             TCP port to be used for debugging
                                     (default: 8765)
  --wasm-pause-waiting-for-debugger  Pauses the execution of Wasm code waiting
                                     for a debugger (default: false)
  --trace-wasm-gdb-remote            Enables tracing of Gdb-remote packets
                                     (default: false)

Note that most of this code is "borrowed" from the code of the Chromium NaCL
GDB-remote stub (located in Chromium in src\native_client\src\trusted\debug_stub).

Implementation details:
- class GdbServer acts as a singleton manager for the gdb-remote stub. It is
  instantiated as soon as the first Wasm module is loaded in the Wasm engine.
- class GdbServerThread spawns the worker thread for the TCP connection.
- class Transport manages the socket connection, in a portable way.
- class Session represents a remote debugging session.
- class Target represents a debugging target and it’s the place where the
  debugging packets will be processed and will implement the logic to debug
  a Wasm engine.

Note: This code began as https://github.com/billti/v8dbg and then moved
into the Edge repository, where I added features gradually and got code
reviews for individual changes. Now, taken in its entirety, it's an
obnoxiously large CL. I'm open to breaking it up into a few chunks if
that would be preferable.

bf8ef94cfe [heap-profiler] Expose 'globalObjectsAsRoots' via inspector interface
This CL adds an argument to the heap profiler that allows to control
whether global objects (e.g. 'window' in JavaScript) are treated as
roots in the heap snapshot. Doing so hides blink-internal details and
is often a good choice when user-JS leaks are investigated. Sometimes,
however, this introduces spurious retainer cycles, which are hard to
debug.

Previously, this option was exposed as a V8 flag. The blink
implications of the build-time V8 flag are now available via
the new blink flag `enable_additional_blink_object_names`.

1d3c4975be [tools] Use instance types of known Maps in v8_debug_helper
If we can read an object's Map pointer but not any data from the Map
itself, we may still be able to accurately describe the object's type if
the Map pointer matches one of the known Maps from the snapshot.
GetObjectProperties uses that data in one of two ways:
- If it is sure that the Map pointer matches a known Map, then it uses
  the type from that Map and continues as if it read the type normally.
- If the Map pointer is at the right offset within a heap page to match
  a known Map, but the caller didn't provide the addresses of the first
  pages in Map space or read-only space, then the type of that Map is
  just a guess and gets returned in a separate array. This gives the
  caller the opportunity to present guessed types to the user, and
  perhaps call again using the guessed type as the type hint.

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.

7e896fe596 [build] Compile compiler with optimizations in fast mksnapshot mode
This changes debug builds [1] to compile src/compiler sources twice:

1. with optimizations, used in mksnapshot to improve performance.
2. without optimizations, linked into d8 and v8 libraries.

While this adds ~200 compilation targets, these can be built in parallel
and should not add much time overall.

This brings mksnapshot runtime back down to 11 seconds on my machine.

[1] The full condition is:
    is_debug && !v8_optimized_debug && v8_enable_fast_mksnapshot

cee2f772c7 [build] disable C++ optimization for mksnapshot code.
By disabling C++ optimizations for code that's only run in mksnapshot,
that is, CSA and Torque-generated code, we can save compile time.
I observed up to 2x improvements of compile time for some files,
while the mksnapshot time did not increase significantly.

c566a40ca2 Always route builds through jumbo.gni for simpler code
jumbo.gni will check whether use_jumbo_build is set or not and
if it's not set it will just check that |jumbo_excluded_sources|
lists do not include non-existing files. That means that there
is little/nothing to lose by always routing v8_source_set that
way, and it adds a bit in build file simplicity and local
checking of |jumbo_excluded_sources|.

An asan bug on Windows breaks the chrome asan bot. This disables asan
for the Torque build step as a workaround.

30caa69fb0 Disable multi_snapshots by default
The multi-snapshot feature is only used on bots, where we need the
ability to execute tests with/without mitigations controllable through a
runtime flag.

This disables the flag by default and only enables it on bot configs.

Note: standard single-snapshot builds silently use the available
snapshot regardless of the value of --untrusted-code-mitigations.
