cdd984ef48 Reland "[wasm] Ensure that only TurboFan code is serialized"
This is a reland of 60ee70bb40.
The wasm c-api flakes were fixed in https://crrev.com/c/2349293.

Original change's description:
> [wasm] Ensure that only TurboFan code is serialized
>
> We have the implicit assumption that Liftoff code will never be
> serialized, and we start relying on that when implementing new features
> (debugging, dynamic tiering).
>
> This CL makes the serializer fail if the module contains any Liftoff
> code. Existing tests are changed to ensure that we fully tiered up
> before serializing a module (similar to the logic in Chromium).
> The "wasm-clone-module" test needs to serialize the module before
> enabling the debugger.
>
> Note that chrome currently only serializes a module after it fully
> tiered up, so that should be fine. If other embedders need the ability
> to serialize a module in an arbitrary state, we will have to fix this
> later. With this CL we will be on the safe side though and (gracefully)
> fail serialization instead of accidentally serializing Liftoff code.

01e59c4bd9 [wasm-gc] Refactoring in preparation of generalizing WasmInitExpr
Motivation: With rtt.sub now allowed in constant expressions, we have
to generalize WasmInitExpr to be able to handle expressions with
operands. This CL prepares the ground for this change and adds no
functionality.

Changes:
- ValueType::heap_representation and HeapType::representation now
  return HeapType::Representation.
- Add ValueType::is_rtt().
- WasmInitExpr:
  - Make kind private. Rename val -> operator, make it private. Add
    accessors.
  - Rename kGlobalIndex -> kGlobalGet.
  - Squash global_index and function_index into index.
  - Add heap_type Immediate. Use it for RefNullConst. TypeOf in
    module-decoder.cc can now fully determine the type of a
    WasmInitExpr.
  - Add class constructors/static method constructors for each Operator
    kind.
  - Delete copy constructor. WasmInitExpr will use std::unique_ptr for
    its operands.
- consume_init_expr now uses a stack.
- A few minor improvements.

ba688c6ec9 [wasm] Rename anyref to externref, anyref flag/feature to reftypes
The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.

3c422d1c5e [snapshot] Clear reconstructable data prior to d8 stress_snapshot run
The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.

With this change, mjsunit tests pass on x64.

The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.

Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

fe0c91cb6c heap: Rework forced GCs
Forced GCs can either be invoked internally or communicate the fact that
they are forced externally via API. Before this CL, all uses were
passing kGCCallbackFlagForced to indicate that the GC was forced.

This flag is used by embedders though to trigger followup actions. E.g.,
it can be used to trigger a follow up call to
GarbageCollectionForTesting() call which requires --expose-gc.

This patch changes the semantics as follows:
- Internal forced GCs use a Heap GC flag (kForcedGC)
- External forced GCs and GC extension use kGCCallbackFlagForced

a183b8be7c [wasm] Clean up WASM_CALL_INDIRECT macros
Fix a TODO from Ben to change the macro argument order to match the
actual order in wasm code.
After this fix, we can remove the individual {WASM_CALL_INDIRECT[0-5]}
macros and implement them via a common variadic macro.

Also, rename {WASM_CALL_INDIRECT_TABLE0} to {WASM_CALL_INDIRECT_TABLE}.
The name was confusing, because this macro explictly allows to set a
table index different from 0. Thus, just drop the "0" in the name.

The individual test changes were done via a vim macro, to avoid manual
errors.

3aa4f05d0c [wasm-c-api] Roll bf31edf: Fix life times of host info
Host info used to be stored on the global reference underlying a Ref;
now it is stored in a JSWeakMap and hence tied to the lifetime of the
actual object on V8's heap.
Additionally, the internal metadata needed for C-API functions is now
stored on the SharedFunctionInfo and no longer overlaps with the host
info mechanism.

5fe29649cf [wasm-c-api] Add anyref support to functions
plus a test that calls a CAPI function directly from C++ (without
the detour through Wasm).
Anyref tables are still unsupported.

e304d80e09 [wasm-c-api] Faster C-to-Wasm entry
powered by a new function Execution::CallWasm and a corresponding,
Turbofan-generated CWasmEntry stub. This entirely sidesteps the
traditional Execution::Invoke -> JSEntryStub path.

cc21e58d30 [owners] Remove redundant OWNERS files in test/
We have a global test/OWNERS that has "file://COMMON_OWNERS".
This CL removes redundant OWNERS files in test/ subdirectories and
removes redundant entries from OWNERS files we need to keep for
special per-file entries.

f5ab7d38be [wasm-c-api] Add tests and fixes
In a new test suite: "wasm-api-tests", using a new binary "wasm_api_tests",
powered by gtest/gmock (like unittests).
Also fix a bunch of issues that these tests uncovered, mostly to ensure
that the stack is walkable.
