63fc14c68b [wasm] Add --no-wasm-lazy-compilation to nooptimization
With shipping lazy compilation, we lose the test coverage for eager
compilation. This is bad, because with PGO, eager compilation may have
a comeback. With this CL we enable eager compilation in the
nooptimization test variant. This variant seems to be the best fit, as
there are no conflicts with existing flags. The --liftoff flag is not a
problem, because Liftoff was anyways the default for eager compilation.

2b133ebc9e [gcmole] Simplify gcmole directives and add tests
This prepares work for speeding up gcmole infrastructure by adding
more checks and testing.

- Add a presubmit check that verifies gcmole directives in gn files.
- Simplify gcmole directives in gn files. Drop all but the
  architecture property as the others were unused. Simplify regular
  expressions.
- Fix some gcmole directives (fly by - only on untested
  architectures).
- Add a python test for the changed function in gcmole.py. There's
  no other testing yet and this starts somewhere. The test simulates
  real BUILD.gn files via checked-in test data.

e69325305b [wasm] Split heap type decoding from validation
When introducing heap type decoding we added some module-specific checks
to the constructor of certain immediates. This broke the previous design
where module-specific checks were done in a separate {Validate} method.

This CL restores that state.

35cc93aa42 [wasm] Detemplatize immediates
The wasm decoder immediates are currently templatized by the {validate}
enum value. They do not need to be though; the only difference is in the
constructor, so the constructor should be templatized instead.

This CL implements that, and also changes the {validate} enum to be a
tag (a typename) instead. This is needed in order to enable template
parameter deduction for the constructor calls (C++ does not allow to
explicitly define the template parameter at constructor calls).

As a nice side effect, this produces nicer symbolized stack traces.
Before:
v8::internal::wasm::Decoder::read_u32v<(v8::internal::wasm::Decoder::ValidateFlag)1>
After:
v8::internal::wasm::Decoder::read_u32v<v8::internal::wasm::Decoder::BooleanValidationTag>

8c7c087812 [heap] Make stack thread-local and introduce stack markers
This CL makes the object keeping stack information thread-local, moving
it from Heap to ThreadLocalTop. In this way, stack scanning will work
correctly when switching between threads, e.g., using v8::Locker.

It also introduces a mechanism for setting a stack marker, to be used
for scanning only the part of stack between its start and the marker
(instead of the current stack top).

a02c56694f Reland "[wasm] Allocate feedback vectors on demand"
This is a reland of commit 4804c4de31.

There are major changes since the previous attempt:
- The WasmLiftoffFrameSetup (formerly WasmGetFeedbackVector) builtin
  now performs as much of the frame setup work as possible, to reduce
  generated code size for each function.
- The WasmLazyCompile builtin/runtime function no longer allocates,
  hence gets frame type INTERNAL, and is un-handlified.

Original change's description:
> [wasm] Allocate feedback vectors on demand
>
> We previously allocated feedback vectors when instantiating the module,
> or when lazily compiling a function. That's not sufficient when there
> are multiple instances of the same NativeModule, or when we eagerly
> tier-down all code for debugging. This patch changes the "get vector from
> instance" sequence at the beginning of every Liftoff function to "get
> or allocate vector"; factored into a builtin call to avoid generating
> more code for every function.

6013fdbac9 [runtime] Cache template objects as JSArray lists keyed on Script
Make several changes to template object caching:

  * Key the cache on Script rather than SFI, so that entries stay alive
    even if the SFI dies (e.g. because its parent is code flushed) but
    can be resurrected (because other functions from the same script can
    recreate it)

  * With the above change, identify the required template object by
    comparing both function literal id and feedback slot id.

  * Change the cache from a linked list of CachedTemplateObjects into an
    ArrayList pointing directly to the template object JSArrays.

  * With CachedTemplateObjects being gone, store the function literal id
    and slot id directly on the JSArray behind private symbols. Fast
    path access to them in the case where the template object has the
    expected map, and look them up in a slow path if the map changed
    (e.g. because the template object was used as a prototype and
    transitioned to a dictionary map).

fb3321ea27 [wasm] Store local types in a plain array
After the let instruction was removed again, the number and types of
locals stays constant throughout the decoding of a function. Hence store
it in a plain array instead of a ZoneVector. This makes the decoder
smaller and saves bounds checks for the "safe libc++".

e9775165b6 [sandbox] Introduce BoundedSize
A BoundedSize is just a regular size_t when the sandbox is disabled.
However, when the sandbox is enabled, a BoundedLength is guaranteed to
be in the range [0, kMaxSafeBufferSizeForSandbox]. This is (currently)
achieved by storing the length shifted to the left, then right-shifting
it when loading it. This guarantees that the top bits are zero.

BoundedSizes are used to ensure safe access to variable-sized buffers,
in particular ArrayBuffers and their views, located inside the sandbox.
If a full size_t is used to represent their size, it may allow an
attacker to "reach out of" the sandbox address space by setting the
length to a very large value. A BoundedSize prevents this.

The function-body-decoder-impl.h header is really heavy, and a comment
at its beginning says that it should only be included for new
implementations of WasmFullDecoder.
While there are other nice reasons to include it (e.g. for the Immediate
types), many includes were not needed.

This CL removes them, and adds other needed includes as needed instead.

d3c1b5a849 [interpreter] Remove await from async generator yield*
Implements the normative change
https://github.com/tc39/ecma262/pull/2819, which removes the await
inside async generator yield*. The delegating iterator result is already
awaited, and this effectively removes an extra tick and unwrapping.

The implementation of `yield` uses the existing AsyncGeneratorYield
builtin, which already performs an Await. It is renamed to
AsyncGeneratorYieldWithAwait.

The implementation of `yield*` uses a new builtin named
AsyncGeneratorYieldNoAwait, which does not perform an Await.
