Previously both tracing implementations would be run side-by-side when
perfetto was enabled with the V8_USE_PERFETTO build flag. This CL
makes them run separately.
Both implementations now use the trace file provided by the user in D8
or the default v8_trace.json.
Add tests for perfetto events (which must be tested differently
due to the proto output format).
Drive-by fix: Fix pass-by non-const ref in GetJSONStrings.
Remove the TraceEvent struct for testing; we can just store a copy of
the protobuf directly.

The client API provides a much simpler interface so that we don't have
to deal with producers, consumers etc. directly. This CL removes all the
code that dealt with the more complex API used previously.
The architecture used here requires that the embedder call into
Tracing::Initialize() to set up the tracing backend. The tracing
controller then connects to this backend when calling
DataSource::Register() and Tracing::NewTrace(). This will ultimately
avoid the need for a virtual call (or two) for every trace event that
need to be dispatched over the API - chrome can provide a backend
and V8 will connect to it opaquely with the same code when tracing is
enabled.

Code relocation info is now always allocated in old-space. Before relocation
info allocated for placeholders and builtins (which get replaced with
trampolines in nosnap builds) would become unreachable. Since read-only space
is not GCed and ReadOnlyHeapIterator doesn't check for reachability,
ValidateSnapshot would fail finding unreachable objects returned by
ReadOnlyHeapIterator.
Because trampoline relocation info gets replaced with canonical one, this only
affects no-embdded-builtins nosnap builds, which don't get much benefit from
read-only relocation info anyway.
A new check has been added to the read-only deserializer to verify that every
read-only object is reachable at mksnapshot-time.
The CombinedHeapIterator iteration order was changed to iterate over
read-only space first, because that's how HeapIterator worked.
This is a reland of 3d1d8eae77
Original change's description:
> [heap] Skip ro-space from heap iterators, add CombinedHeapIterator.

> Read-only space sharing requires an iterator independent of heap. This

The previous code assumed that trap handling was a global concept, defined
by function trap_handler::UseTrapHandler(). This CL does the first step
in changing the decision to be specifiable at a module level.
Therefore trap_handler::UseTrapHandler() is replaced by
trap_handler::IsTrapHandlerEnabled(), and communicates if compilation
supports the use of trap handlers (but still allowing the use of
bounds checking on memory accesses).
It then refactors the classes ModuleEnv and WasmCompiledModule to have
a field "use_trap_handler" that specifies if traps should be used for
the memory accesses in the module being compiled.

Several future enhancements are planned before turning this on by default.
Obviously, the additional checks will be added to MaybeHandleFault. We are

arguments.h is one of the headers including objects-inl.h. Files needing
objects-inl.h used to innocently pull in debug.h, so that needs to be fixed now
too.

Now callers of Heap::CollectGarbage* functions need to
specify the reason as an enum value instead of a string.
Subsequent CL will add stats counter for GC reason.

Rebuilding (after touching certain files) is crazy slow because
includes are out of control. Many of these files we need to rebuild are
cctests which pull in more includes than they need.

This allows using icu data, bundled in the icudtl.dat file,
to be loaded automatically from a default location
side-by-side with the executable.
The v8 stand-alone default is still to use statically
linked ICU data, but this will be switched in a separate
follow-up CL.

- Make the API look like v8::V8::InitializeICU.
(That is: A static method call, not an object to be created on the stack.)
- Fix path separator on Windows, by calling base::OS::isPathSeparator.
- Move into API, so that it can be called by hello-world & friends.
- Actually call it from hello-world and friends.

There is only one use case for it: String.prototype.search converts a
string argument into a RegExp. The cache is used to avoid repeating that
conversion. However, this does not make the added complexity worthwhile.
