I did the implementation with a runtime function. I extracted some code
from the implementation of table.get.
By accident I formatted anyfunc.js. However, since it's an improvement,
I don't want to undo it. I didn't change anything in the older tests
though, I only added new tests at the end.

Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.
Patchset 1 was auto-generated by using this clang AST matcher:
callExpr(
callee(
cxxMethodDecl(
hasName("start"),
ofClass(hasName("v8::internal::Vector")))
),
argumentCountIs(0))
Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

calls to tables other than table 0. Whenever the Liftoff code got

Original message:
With this CL it is possible to use any anyfunc table in call-indirect,
not just the first table.
The current implementation is based on runtime calls. This is just an
initial implementation which should be replaced by a
dispatch-table-based eventually. However, this implementation allows

This prepares a refactoring to add and publish compilation results in
batches. For this, we need to separate the two phases, so that we can
lock the module, allocate all the code space, release the lock, copy
the code, lock the module, publish the code, and release the lock
again.
In particular, this CL does the following:
1) It removes the {AddOwnedCode} method. The functionality of creating
the {WasmCode} and memcpy'ing the instruction into that is done in
the other {Add*Code} methods. Adding to {owned_code_} is done in
{PublishCode}.
2) {PublishInterpreterEntry} is now functionally equivalent to
{PublishCode}, so it's removed.
3) After {AddCode}, the caller has to call {PublishCode}. In a
follow-up CL, this will be called in batches (first {AddCode} them
all, then {PublishCode} them all).
4) {AddCompiledCode} now assumes that the {WasmCompilationResult}
succeeded. Otherwise, the caller should directly call {SetError} on
the {CompilationState}.
5) {PublishCode} is now the chokepoint for installing code to the code
table, the owned code vector, the jump table, and setting interpreter
redirections. It replaces previous direct calls to {InstallCode} or
explicitly adding to {owned_code_}.
6) Increasing the {generated_code_size_} counter is now done in
{AllocateForCode}, which is the chokepoint for allocating space for
generated code. This way, we will only increase this counter once
once we allocate in batches.

We need to ensure that the NativeModule stays alive while any
{BackgroundCompileScope} exists, because during that time we hold
shared ownership of the mutex in the {BackgroundCompileToken}. If the
{NativeModule} dies during that period, we would need to get exclusive
ownership of the mutex and deadlock.
This change requires holding a {std::weak_ptr<NativeModule>} in the
BackgroundCompileToken instead of a raw pointer, hence it can only be
initialized after the NativeModule was created. This is done via a
separate {InitCompilationState} method.

This removes an outdated section order check from {CreateNewBuffer} and
relies solely on the checks done in {ProcessSection}. Those checks are
more comprehensive and will remain coherent with synchronous decoding.

Googletest is (at last) converging with industry-standard terminology
[1]. We previously called test suites "test cases", which was rather
confusing for folks coming from any other testing framework.
Chrome now has a googletest version that supports _TEST_SUITE_ macros
instead of _TEST_CASE_, so this CL cleans up some of the outdated usage.

In the wasm streaming decoder error position test, do also check the
error messages generated. This revealed messages that were not quite

For macros expanding to function definitions, I removed the spurious ; after
macro invocations. For macros expandign to function declarations, I made the ;
required and consistently inserted it.
No behavior change.

This removes most macros from the function body decoder unittest. It
makes the {Validate} method (and the new {ExpectValidates} and
{ExpectFailure}) templates, to receive the code in different formats.
Drive-by: Rename "verify" to "validate".

Anyref parameters can exist across GC runs. Therefore the GC has to
know where anyref parameters are on the stack so that it can mark them
in its marking phase, and update them in the compaction phase.
Already in a previous CL we grouped all anyref parameters so that they
can be found more easily in a stack frame, see
https://crrev.com/c/1371827. In this CL we implement the stack scanning
itself.
Note that anyref parameters are not scanned while iterating over the
caller's frame (to which they actually belong), but while iterating
over the callee's frame. The reason is that with tail-calls, only the
callee knows how many tagged stack parameters (aka anyref parameters)
there are.

The WasmCodeManager held a list of all Isolates that use the
WasmEngine/WasmCodeManager (those two are 1:1).
Since we want to move all isolate-specific tasks (like code logging and
compilation callbacks) to the WasmEngine, this CL moves this management
from the WasmCodeManager to the WasmEngine. We now have a bidirectional
mapping from NativeModules to the Isolates that use them, and from an
Isolate to all the NativeModules it uses (n:n).
The IsolateData struct will be extended in follow-up CLs to hold things
like the ForegroundTaskRunner. The Isolate* in the NativeModule /
CompilationState will eventually be removed.

We often use ResultBase or VoidResult to store or pass wasm errors
(errors with locations). This CL extracts a WasmError class which can
store an error (can also be empty), and Result<T> which stores an error
