This CL is pretty mechanical; I just iterated through some Torque
classes making the following changes:
- Use @generateCppClass if it seems easy to
- Use @generatePrint if the existing printer doesn't do anything special
- Fix up any imprecise field types
It also includes two minor changes to implementation-visitor:
- Add a new -inl.h file with the things needed for
torque-generated/class-definitions-tq.cc so we don't need to keep
changing the compiler when we add @generateCppClass.
- Avoid emitting incorrect accessors for ExternalPointers. This isn't
strictly necessary for correctness, as the accessors defined in C++
already hide the ones inherited from generated code, but it makes me
feel safer.

Passing an isolate to {RecompileNativeModule} feels wrong, since
compilation and the generated code are totally isolate-independent. In
fact, the isolate is only used for updating counters.
Instead of passing the counters instead, this CL just refactors the code
to support a nullptr for the counters everywhere (some code paths
already supported that). The few recompilation would not make a
significant difference in the histograms anyway, and even have the risk
of skewing the data.
Drive-by 1: Rename {TierUp} to {StartTierUp} and update comments.
Drive-by 2: Remove non-actionable TODO.

This patch implements f32x4.pmin, f32x4.pmax, f64x2.pmin, and f64x2.pmax
for x64 and interpreter.
Pseudo-min and Pseudo-max instructions were proposed in
https://github.com/WebAssembly/simd/pull/122. These instructions
exactly match std::min and std::max in C++ STL, and thus have different
semantics from the existing min and max.
The instruction-selector for x64 switches the operands around, because
it allows for defining the dst to be same as first (really the second
input node), allowing better codegen.
For example, b = f32x4.pmin(a, b) directly maps to vminps(b, b, a) or
minps(b, a), as long as we can define dst == b, and switching the
instruction operands around allows us to do that.

Also, forbid allocating any more AST strings after AstValueFactory
internalization, by nulling out the Zone. Add an InternalizePartial

to be able to allocate after internalizing (e.g. internalization before

Implementing 64-bit CompareExchange on arm requires a lot of registers,
with the additional constraint that the low-word register of new_value

high-word registers have a register code that is by one higher than the
register code of the low-word register.
This register allocation is achieved by assigning fixed registers to

The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the

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.

Changes:
- Implement subtyping for reference types (ref s) and (optref s),
where 's' is a struct type.
This CL does *not* implement subtyping between struct and function
types. Also, it does not handle i31refs and eqrefs.
- Implement struct.set.
- Change struct.get to accept an optref as argument, as required by the
standard.
- Allow locals to store objects of ref and optref types.
- Add a test for struct.set and optref locals. Modify the test for
struct.get accordingly.

This removes the interpreter entry stubs, which are used to redirect
specific wasm functions to the interpreter. It is only needed when
mixing JS code with interpreted Wasm code, otherwise the test functions
just call the interpreter directly.
Thus a lot of tests that contain such interaction between JS and Wasm
need to be restricted to execute in Liftoff and TurboFan only.
After this CL, the WASM_INTERPRETER_ENTRY frame type and the
corresponding WasmInterpreterEntryFrame are dead, and will be removed in
a follow-up CL.

The existing implementation needed uses of the outputs of an
AtomicExchange to allocate registers for the result value. However,
these uses are not guaranteed to exist. With this CL temp registers
get allocated if the uses don't exist.

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

When a background thread fails to allocate, it requests a GC and
retries the allocation afterwards. Make second allocation more likely

TLABs of LocalHeaps also need to be invalidated before the GC.
