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.

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.

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

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.

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

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.
