3e546664e6 [roheap] Move read_only_heap() from heap to isolate
Once read-only space is not a Heap space it makes little sense to have
it in the Heap class.

878ccb33bd [cleanup] Avoid {Object::operator->}
This CL was generated by an automatic clang AST rewriter using this
matcher expression:

  callExpr(
    callee(
      cxxMethodDecl(
        hasName("operator->"),
        ofClass(isSameOrDerivedFrom("v8::internal::Object"))
      )
    ),
    argumentCountIs(1)
  )

The "->" at the expression location was then rewritten to ".".

9c06209306 Reland "[heap] Skip ro-space from heap iterators, add CombinedHeapIterator."
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

> [heap] Skip ro-space from heap iterators, add CombinedHeapIterator.
>
> Read-only space sharing requires an iterator independent of heap. This
> also enables future removal of read-only space from heap.

b60eb45c82 [cctest] Reenable V8 disposal
This was disabled in 2014 (https://crrev.com/267383002), together with
a comment about a broken serializer. The conditional v8 initialization
was since then moved back to be unconditional, but the TearDown was
never restored.
Now we need it for wasm, since during tear down the wasm engine
synchronizes on all background compile jobs. Omitting this leads to
uses of the disposed platform (see https://crrev.com/c/1429861).

4064757cbf [cleanup] Clean up base::EnumSet
After moving to its own header, this CL cleans up some parts of the
interface. It fixes names and const-declarations of simple accessors,
and adds a named constructor to make it explicit that an EnumSet should
be constructed from an integral value.
Also refactor the use in cctest.h to have less statically declared
constants. Instead, just create the set of extensions in the individual
tests.

0d5de9ad9b [wasm] First step of refactoring trap handling to be per module.
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.

With this CL, {CreateDefaultPlatform} returns a unique_ptr to indicate
that the caller owns the returned memory. We had several memory leaks
where the memory of the DefaultPlatform did not get deallocated.

In addition, the {TracingController} of the {DefaultPlatform} also gets
received as a unique_ptr. Thereby we document that the {DefaultPlatform}
takes ownership of the {TracingController}. Note that the memory of the
{TracingController} was already owned by the {DefaultPlatform}, but it
was not documented in the interface, and it was used incorrectly in
tests.

b9e4bbb0a0 Remove CcTestArrayBufferAllocator
This is almost identical to V8's default array buffer allocator.  The only
difference is that 0 byte allocations are changed into 1 byte allocations.  We
do not seem to need this behavior, so it does not seem worth maintaining yet
another allocator.

118c376fcb [wasm] Initial signal handler
This is basically the minimum viable signal handler for Wasm bounds checks.
It includes the TLS check and the fine grained instructions checks. These
two checks provide most of the safety for the signal handler. Future CLs will
add code range and data range checks for more robustness.

The trap handling code and data structures are all in src/trap-handler, with
the code that actually runs in the signal handler confined to
src/trap-handler/signal-handler.cc.

This changes adds a new V8 API that the embedder should call from a signal
handler that will give V8 the chance to handle the fault first. For hosts that
do not want to implement their own signal handler, we include the option to
install a simple one. This simple handler is also used for the tests.

When a Wasm module is instantiated, information about each function is passed
to the trap handler, which is used to classify faults. These are removed during
the instance finalizer.

Several future enhancements are planned before turning this on by default.
Obviously, the additional checks will be added to MaybeHandleFault. We are
also planning to add a two-level CodeObjectData table that is grouped by
isolates to make cleanup easier and also reduce potential for contending on
a single data structure.

The v8 stand-alone default is still to use statically
linked ICU data, but this will be switched in a separate
follow-up CL.
