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.

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.

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.

Port the CompilerDispatcher to use the Jobs API, instead of its own
hand-rolled worker management.
This required some re-thinking of how testing is handled, since the
tests want to be able to
a) Defer calls to PostTask/Job, to actuall post the jobs later. This
was easy enough with PostTask, since we could simply store the task
in a list and no-op, but PostJob has to return a JobHandle. The
tests now have a DelayedJobHandleWrapper, which defers all method
calls on itself, and because of all the unique_ptrs, there's also
now a SharedJobHandleWrapper.
b) Wait until tasks/jobs complete. Returning from a Task meant that
the task had completed, but this isn't necessarily the case with
JobTasks; e.g. a job might be asked to yield. This patch hacks
around this by Posting and Joining a non-owning copy of the
requested JobTask, and then re-posting it once Join returns.

This is a reland of 45227ffdb4
Differences:
- Handle one more flags conflict in variants.py.
- Disallow %VerifyType without --concurrent-recompilation.
Original change's description:
> [turbofan] extend type asserts to cover all JS types
>
> Extend type assertions to all types covering JavaScript values.
> This is achieved by allocating type representations on the heap using
> newly defined HeapObject subclasses. To allocate these in the compiler,
> we disable concurrent compilation for the --assert-types flag for now.
>
> Fix two type errors that came up with the existing tests:
> 1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of
> OtherObject.
> 2. OperationTyper::NumberToString(Type) can type the result as the
> HeapConstant Factory::zero_string(). However, NumberToString does
> not always produce this string. To avoid regressions, the CL keeps
> the HeapConstant type and changes the runtime and builtin code to
> always produce the canonical "0" string.
>
> A few tests were failing because they check for truncations to work
> and prevent deoptimization. However, AssertType nodes destroy all
> truncations (which is by design), so these tests are incompatible
> and now disabled for the assert_types variant.
>
> Drive-by fix: a few minor Torque issues that came up.

Implement `LiftoffAssembler::emit_i16x8_sconvert_i32x4` for riscv.
Add tests for rvv integer and floating-point instructions.
Add simulator support for rvv instructions, e.g. `vfmadd`, `vnclip`.
Fixed order of operands for `vfdiv.vv`.

The stack-switching test is not expected to pass yet if a GC happens
in the runtime call or in the wasm call.
