7f92ad0ab6 [test] refactor testsuite configuration
Every testsuite configuration consist of at least 30% code duplication.

The code age ranges from 10 years old to 5 years old. Implementing anything that
touches the testsuite code becomes a technical fight to the death.

This CL removes all the duplication by refactoring the common functionality.

This CL contains structural changes without any logical changes % small bug
fixes.

eb18edb4f5 [json] Extend JSON#stringify error message for circular structures

constructors and keys involved in the circle:

const a = {};
a.arr = [];
a.arr[0] = a;
JSON.stringify(a);

TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Object'
    |     property 'arr' -> object with constructor 'Array'

40eb442783 [test] Fix expectations in WebKit JSON.stringify tests
The reference implementation used in the tests does not fully match
the spec, so for the diverging cases we need to explicitly specify
the correct expectation.

Every single change in this patch has been verified against every
major JavaScript engine using eshost + jsvu. All implementations
match the spec (and the V8 implementation), with the following two
exceptions:

- One expectation was wrong because of a JavaScriptCore bug (that
  is, we inherited the incorrect expectation when importing the
  tests from WebKit). A comment was added for that one.
- This work resulted in the discovery of bugs in Moddable/XS:

Many tests were already skipped in debug mode, but they kept running on CQ
which sets dcheck_always_on, probably equally slow.

Some other tests are marked as slow based on a recent run of the arm64 sim
trybot.

Clang is known to use a lot of stack space for Debug builds, so
this patch lowers the recursion depth of that test after recent
changes made Debug-mode stack frames a bit larger.

a bit of Debug-mode stack space.

952c097679 [builtins] Port Array.p.join to Torque.
This also includes ports of Array.p.toString and Array.p.toLocaleString.
Many parts of the old JS implementation are preserved, because
TypedArray.p.join still relies on it.  These will be removed once
TypedArray.p.join is ported to Torque.

To simplify implementation, special handling of extremely sparse arrays
has been removed.

Performance improvements vary by array size, elements, and sparse-ness.
Some quick numbers and graphs are here:

5f8a42727d Reland "[interpreter] Add bytecode for leading array spreads."
This is a reland of 1c48d52bb1.

It turned out that IterableToList doesn't always behave according to
the ES operation with the same name. Specifically, it allows holey arrays
to take its fast path, which produces an output array with holes where
actually "undefined" elements should appear.

This CL changes the version of IterableToList that is used for spreads
(IterableToListWithSymbolLookup) such that holey arrays take the slow path.
It also includes tests for such situations.

fd334b3216 [builtins] Enable Torque Array.prototype.splice
Before, splice was implemented with a C++ fast path and a
comprehensive JavaScript version.

This impl. is entirely in Torque with a fastpath for SMI,
DOUBLE and OBJECT arrays, and a comprehensive slow path.
The same level of "sparse" array support as given by the
array.js implementation is included.

This reland addresses several issues:

* Removed "sparse" array support from splice.
* Addressed ClusterFuzz issue 876443:
  The test and code that uses the fix is in this CL.
  The fix in isolation can be seen here:
  https://chromium-review.googlesource.com/c/v8/v8/+/1199403
* Removed dead code in elements.cc

c4dabe1774 [test][mips64]: Skip dfg-int-overflow-in-loop on simulator.
If test webkit/dfg-int-overflow-in-loop is executed with option --noopt,
execution will be too slow on simulator. Therefore, this test will be
skipped on MIPS64 simulators.

8e7737cb58 [builtins] Refactor promises to reduce GC overhead.
This implements the ideas outlined in the section "Microtask queue"
of the exploration document "Promise and async/await performance" (at
https://goo.gl/WHRar2), except that the microtask queue stays a linear
FixedArray for now, to avoid running into trouble with the parallel
scavenger. This way we can already save a significant amount of
allocations, thereby reducing the GC frequency quite a bit.

All items on the microtask queue are now proper structs that subclass
Microtask, i.e. we also wrap JSFunction and MicrotaskCallback jobs
into structs. We also consistently remember the context for every
microtask (except for MicrotaskCallback where we don't have a
context), and execute it later in exactly that context (as required
by the spec anyways for the Promise related jobs). Particularly
interesting is the PromiseReactionJobTask and its subclasses, since
they are designed to have the same size as the PromiseReaction. When
we resolve a JSPromise we just take the existing PromiseReaction
instances and morph them into PromiseFulfillReactionJobTask or
PromiseRejectReactionJobTask (depending whether you "Fulfill" or
"Reject"). That way the JSPromise class is now only 6 words instead
of 10 words.

Also the PromiseReaction and the reaction tasks can either carry a
JSPromise (for the fast native case) or a PromiseCapability (for the
generic case), which means we don't always pay the overhead of having
to also remember the "deferred resolve" and "deferred reject" handlers
that are only relevant for the generic case anyways.

It also fixes a spec violation where we called "then" before we actually
enqueued the PromiseResolveThenableJob, which is observably wrong.
Calling it later has the advantage that it should be fairly
straight-forward now to completely avoid it for native Promise
instances.

This seems to save around 10-20% on the various Promise benchmarks and
micro-benchmarks. We expect to gain even more as we're now able to
inline various operations into TurboFan optimized code easily.
