This improves the performance of initializing instances with
private methods by 5-6x and makes it on par with initializing
instances with only public methods.

Drive-by: remove the obsolete AddPrivateField runtime function

Refactor the GetValueType function. Emit a meaningful
initializer for every ref type in globals instead of an
empty one. Avoid the non-nullable recursive type by only
allowing indices that are strictly less than the current index.

Since early regexp errors were implemented in
crrev.com/a56874d3, the JS parser
calls into the regexp parser to validate the regexp literal syntax.

For these calls, the JS parser passes its Zone to the regexp parser.
This means that scripts with multiple regexp literals are all parsed
using the same Zone memory. Very large scripts with many (think
hundreds of thousands) regexp literals may thus run out of memory
whereas previously they would parse and run successfully.

This CL fixes the OOMs by resetting the state of the JS parser Zone
around regexp parser calls. We introduce a new ZoneScope class,
similar to HandleScope, which controls the lifetime of zone objects
allocated within its scope. In other words:

 {
   ZoneScope zone_scope(zone);  // Store zone state S.
   // ... Allocate objects O in zone.
   // zone is now in state S'.
 }
 // zone_scope goes out of scope, reset zone to state S. Objects O
 // are freed and no longer usable.

This patch refactors the ClassFields benchmarks and makes the results
detection work properly. Previously the errors weren't caught since
the ClassFields benchmarks don't get run in the perf_integration
step in the CI.

- Instead of putting different configs (single/multiple fields, type
  of fields, etc.)in the JSON configuration, we now group the related
  benchmarks into the same script and run the different configurations
  in the scripts directly. Only the optimization status is now
  controlled in JSON. All the class fields definition benchmarks are
  merged into initialize-class.js.
- Update the number of local iterations of evaluate-class.js to 100
  (similar to most of other benchmarks) to keep the time spent on
  this benchmark similar to that of other benchmarks.

In addition, copy the configs to JSTests3 so that the benchmarks gets
run by the perf_integration step and we can see the graphs on
http://chromeperf.appspot.com/report. These can be removed
when the ClassFields benchmark results are generated there too.

Design doc:  https://bit.ly/3jEVgzz

Summary:
We change the context for WasmJSFunction and WasmCapiFunction from a
tuple containing the instance to a triple WasmAPIFunctionRef =
{isolate root, context, callable}. This way we do not have to maintain
the correct instance at runtime. Also, a few places in the code get
simplified.

Changes:
- In WasmGraphBuilder, support having a WasmAPIFunctionRef at parameter
  0.
- Remove unpacking of (instance, callable) tuple from code generators.
- Remove the part in WasmGraphBuilder and LiftoffCompiler that used to
  set the instance field of the function reference.
- Modify code that handles the 'ref' field in wasm-objects.*, factory.*
  and c-api.cc.
- Fix the recorded safepoint address for arm when calling a C function
  from wasm.
- (Drive-by) Remove WasmAllocatePair.

This reverts commit 35a6eeec.

Reason for revert: TSAN failures like https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN/39084/overview

Original change's description:
> [off-thread] Allow off-thread top-level IIFE finalization
>
> Allow off-thread finalization for parallel compile tasks (i.e. for top-
> level IIFEs).
>
> This allows us to merge the code paths in BackgroundCompileTask, and
> re-enable the compiler dispatcher tests under the off-thread
> finalization flag. Indeed, we can simplify further and get rid of that
> flag entirely (it has been on-by-default for several releases now).

There is a bit of a contradictory register requirement in the
instruction selector for i64x2.mul. We want dst == lhs (when AVX not
supported), but we also want lhs and rhs to be unique (to ensure that
that they don't alias the temp).

We remove the requirement for dst == lhs, since the code gen can handle
both cases (dst == lhs, dst != lhs), at the expense of 1 movaps.
