Currently the fuzzer only tests Turbofan and Liftoff in isolation. In
order to test that both tiers use the same ABI, it should also test
calls from one tier to the other.
This CL introduces a new flag which controls which function will be
compiled by which tier, and uses that in the fuzzer.

When calling an import which is an exported wasm function, the
interpreter needs to look through the jump table to find the

We already had that logic for indirect calls, but it was missing for

This CL adds the simplest version of a trap handler fallback. At
instantiation time, we check whether the module was compiled to use
trap handlers and the memory is guarded. If the memory is not guarded
but the module is supposed to use trap handlers, we recompile the
module with bounds checks so that we can use an unguarded memory.
The compiled module is replaced with a bounds checking version, meaning
future instances from this module will also use bounds checks.
Some likely desirable features that are current missing but can be
added future CLs include:
* Disabling trap handler mode entirely.
* Recompiling all old instances so that trap handler and bounds checked
code does not coexist in the same process.

The typical use of assertThrowsEquals is to check that a specific
object is thrown. However, assertEquals only does a proper equality
check for primitive types, not for complex types. Using assertSame
does a reference equality check on objects, which is more what you
would expect from assertThrowsEquals. For exception kind testing,
assertThrowsEquals actually did not work correctly, assertThrows is
better for that case.

This makes stack checks in WasmCode independent of the underlying
Isolate by loading the limit address from the WasmInstanceObject instead
of embedding it into the instruction stream. It hence removes the last
use of the Isolate field from WasmGraphBuilder.
Additionally this introduces the notion of a "runtime stub" which
represents stub code global to the NativeModule that can be directly
called from each WasmCode in the same module. These stubs can act as
trampolines via which Isolate-independent WasmCode can enter other V8
builtins or runtime functions that remain Isolate-dependent. They will
eventually replace the current "trampoline" in a NativeModule.

The flag lets d8 wait for async compilation of WebAssembly to finish

According to the spec, exported wasm functions should not have a
[[Construct]] method, hence they don't have a prototype.

There is a clear mistake of using kWasmF64 instead of kWasmF32.

When calling a function through a function table, check whether the
instance of the called function differs from the current instance, and
in that case call the other function via a c-wasm-entry instead of
interpreting it.
The c-wasm-entry needs to pass the wasm context, so this CL changes
this to receive the wasm context as parameter instead of embedding the
context of the calling instance.
