4672b86586 [wasm] Implement the ref.func instruction
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.

4b0f9c856e [cleanup] Use Vector::begin instead of Vector::start
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.

98b8715427 [wasm][cleanup] Using 'using' instead of 'typedef'
Even though both are allowed in the style guide, it recommends to use
'using', as its syntax is more consistent with the rest of C++.
This CL turns all typedefs in wasm code to 'using' declarations.

2d9ec0a420 Reland: [wasm][anyref] Add support of call-indirect for multiple tables
The reason for the revert was that Liftoff did not bail out on indirect
calls to tables other than table 0. Whenever the Liftoff code got
executed, the test would fail.

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
us to move forward with the anyref proposal implementation.

25d8a157b1 [wasm] Split adding code from publishing it
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.

3df442d738 [wasm] Keep NativeModule alive in BackgroundCompileScope
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.

4d9381baa6 test: Replace _TEST_CASE_ with _TEST_SUITE_.
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.
