01dc5707e4 [wasm] Generate code for the table.get and table.set instructions
This CL contains the following changes:
(1) Allocate memory for WasmTables in the WasmInstance.
    - We extend the WasmInstance by a FixedArray which stores
      references to the WasmTables.
(2) Rename the name of the backing store of WasmTables from `functions`
    to `elements`.
    - The name `functions` just does not fit anyref tables.
(3) Generate code with TurboFan for table.get and table.set.
(4) Extend wasm-module-builder.js to be able to generate modules with
    multiple tables.
(5) Add  mjsunit tests to test table.get and table.set.

Given a map, its HasNonInstancePrototype bit in bit_field can differ
from the same bit in that map's root map. If that is the case just
return false from the equivalence check. (Currently, we just assert
that bit_field is the same for a map and its root map.)

58ebbf3475 Fix JSTest/Proxies/Set.*Trap tests to return true from the trap
The spec specifies that a non-true return values from the trap functions
should be treated as error in the strict mode. With the new lazy feedback
effort inferring the language mode is expensive and causes regression on
these tests. Since the test doesn't actually need to test this, fixing
them to return true would help test the performance of calling the trap
without the unnecessary overhead of inferring the language mode.

486ec80a7d [parser] Reset expression_scope_ stack to nullptr when parsing a function body
That way we can properly walk the active ambiguous stack of expressions and
stop where it's non-ambiguous. In the bug we would have forced context
allocation of "this" in an outer function because an inner function was parsed
as part of an arrow function head and "this" was referenced. That caused the
ambiguous arrow head scope to be marked, even though the reference came from a
non-ambiguous function.

Introduce a PREMONOMORPHIC state to StoreGlobalIC

It's used rather narrowly for now -- only when we run into an
interceptor during the lookup. After the call to SetProperty, we know
more. That is, the interceptor was only there because it's a new
property, and the call to SetProperty ends up creating it.

By delaying the initialization of the IC, we recognize the (now)
created property, and can provide good feedback downstream to
TurboFan.

3724a12549 Reland "[error] extend error stack w/ function parameters"
This is a reland of 97628eeeb9.

Original change's description:
> [error] extend error stack w/ function parameters
>
> Extend FrameArray to hold weak references to parameters forfunctions in
> the call stack. The goal here is to provide more metadata for postmortem
> tools (such as llnode), especially in cases of rethrowing (this will be
> particularly useful when using postmortem with promises on Node.js).
>
> Besides postmortem, these changes allow us to print a more detailed
> stack trace for errors with parameters types (or even values), which can
> be useful since JavaScript functions can receive any number of
> parameters of any type, and having a function behave differently
> according to the number of parameters received as well as their types is
> a common pattern on JS libraries and frameworks.

4c65986a44 [heap] Rework incremental marking scheduling
The new scheduling reduces the main thread marking performed in
tasks and on allocation. It is based on two counters:
- bytes_marked,
- scheduled_bytes_to_mark.

The bytes_marked accounts marking done both the main thread and
the concurrent threads. The scheduled_bytes_to_mark increases based
on allocated bytes and also based on time passed since the start
of marking. The main thread steps are allowed to mark the minimal
amount if bytes_marked is greater than scheduled_bytes_to_mark.

This also changes tasks posted for marking. Before only normal
tasks were posted. Now delayed tasks are posted if the marker is
ahead of schedule.

For the initial implementation we simply keep the capacity of
the young large object space in sync with the capacity of the
new space. The only subtlety is that we allow at least one
large object independent from its size. So it may exceed the
capacity of the space.

This also fixes setting of the large page flags for incremental
marking.

ea86509424 Constant field tracking for arrays.
This adds constant field tracking for arrays. To prevent changing the
field in some other elements-kind-branch of transition tree, we only
use the const information in the optimizing compiler if the map is not
an array map or if the map is stable (since stable maps cannot
transition to a different elements-kind-branch without deopt).

8c30a2ccc0 [testrunner] migrate testsuites to lazy loading
V8 test suites return tests by loading them into memory up-front. Up-front
loading has memory and loading-time overhead for the testrunner.

This CL converts the test-suites to load tests during the test run in parallel.

After CL, most test suites start running immediately and all test suites start
running after 3 seconds on a modern SSD.

This CL eliminates the 200 MiB memory spikes that causes memory problems in mac
minis.

Overhead of running test262 before CL:
Line #    Mem usage     Increment   Line Contents
=================================================
   264  225.760 MiB 195.8.000 MiB         tests = self._load_testsuite_generators(args, options)
-------------------------------------------------
Overhead of running test262 after CL:
Line #    Mem usage    Increment   Line Contents
================================================
   264   28.840 MiB    0.000 MiB         tests = self._load_testsuite_generators(args, options)

3f2b501729 [parser] Handle 'this' with a special ThisExpression rather than VariableProxy
"this" is a very common expression. By using a single ThisExpression object
we can both avoid allocating many unnecessary VariableProxies and specialize
the resolution of this since we know where it's declared up-front. This also
avoids having to special-case "this" reference handling in the paths that would
behave differently for "this" than for regular references; e.g., with-scopes.

The tricky pieces are due to DebugEvaluate and this/super() used as default
parameters of arrow functions. In the former case we replace the WITH_SCOPE
with FUNCTION_SCOPE so that we make sure that "this" is intercepted, and still
rely on regular dynamic variable lookup. Arrow functions are dealt with by
marking "this" use in ArrowHeadParsingScopes. If the parenthesized expression
ends up being an arrow function, we force context allocate on the outer scope
(and mark "has_this_reference" on the FUNCTION_SCOPE so DebugEvaluate in the
arrow function can expose "this").

The CL also removes the now unused ThisFunction AST node.

ac73e1d52b Reland "[test] Check for illegal uses of mjsunit methods"
This is a reland of a9e93572d4

Original change's description:
> [test] Check for illegal uses of mjsunit methods
> 
> The assertThrows and assertDoesNotThrow methods expect either a
> function to execute, or a string to eval. In several tests however we
> accidentally passed the *result* of the statement to be tested instead
> of the code.
> This CL adds check to catch such error early, and removes wrong uses.
> In most places, we do not need to use assertDoesNotThrow anyway,
> because exceptions are handled as test failures.
> 
> Drive-by: Unify catch syntax in mjsunit.js and make sure to propagate
> MjsUnitAssertionErrors correctly.

Set entries return an array with the value as first and second entry.
As such these are considered key value pairs to align with maps
entries iterator.
So far the return value was identical to the values iterator and that
is misleading.

This also adds tests to verify the results and improves the coverage
a tiny bit by testing different iterators.

06ba822ead Map update for integrity level transitions.
This adds support for integrity level transitions (preventExtensions,
seal and freeze) to MapUpdater and Map::TryUpdate.

In both cases, we first try to detect whether there were integrity
level transitions in the transition tree to the old map and make note
of the most restrictive integrity transition and the map just before
the transition (integrity-source-map). Then we find an appropriate root
(based on integrity-source-map's elements kind) and replay the
transitions based on the integrity-source-map's descriptor
array. Finally, if we saw an integrity level transition in
the beginning, we will find-or-create that transition (on the
updated version of integrity-source-map).

For the following micro-benchmark, we get about 10x speedup.

```
function C() {
  this.x = 1;
  Object.seal(this);
  this.x = 0.1;
}

const start = Date.now();
for (let i = 0; i < 1e7; i++) {
  new C();
}
console.log("Reconfigure sealed: " + (Date.now() - start));
```

Before:
> Reconfigure sealed: 5202

After:
> Reconfigure sealed: 479

a1b431d7d3 [serializer] share class positions tuple across contexts
Class positions is a struct that stores the start and end positions of a class
literal. It is stored both on class objects, and the template used to
instantiate class objects.

The template is reachable from the bytecode array and therefore serialized by
the startup serializer. Class objects are context-dependent and therefore
serialized by the partial serializer. Serializing class positions from both
serializers violates the assumption that we don't serialize any object twice.

f0d69fc913 [test] Modernize value helpers
This CL changes the usage pattern from
FOR_XXX_VALUES(i) { Use(*i); }
to
FOR_XXX_VALUES(i) { Use(i); }
which is way more intuitive.

Note that the replacement in the uses was done via regular expression,
so it's purely mechanical. In two locations I removed unneeded braces
around the macro, because they confused clang-format.
I plan to do more cleanups (remove redundant assignments within the
FOR_XXX_VALUES body) in a follow-up CL.

a9e93572d4 [test] Check for illegal uses of mjsunit methods
The assertThrows and assertDoesNotThrow methods expect either a
function to execute, or a string to eval. In several tests however we
accidentally passed the *result* of the statement to be tested instead
of the code.
This CL adds check to catch such error early, and removes wrong uses.
In most places, we do not need to use assertDoesNotThrow anyway,
because exceptions are handled as test failures.

Drive-by: Unify catch syntax in mjsunit.js and make sure to propagate
MjsUnitAssertionErrors correctly.

4863a5505f [typedarray] Replace quicksort with mergesort to make TA#sort stable
This CL replaces the current TypedArray#sort with a simpler mergesort.
The fastpath when the user does not provide a comparison function
is still used.

In addition, TypedArray#sort now converts all elements in the
TypedArray to tagged values upfront, sorts them and writes them
back into the TypedArray as the final step.

According to spec https://tc39.github.io/ecma262/#sec-object.assign,
https://tc39.github.io/ecma262/#sec-ordinaryownpropertykeys, object.assign should copy symbols last. The current implementation ignores that order.
The idea of the fix here is to do iteration twice, one to skip symbol first then one to skip string.

This adds support for handling exceptions between different frames of
one single interpreter activation. Frames are dropped until a local
handler is found. If none is found in the current activation then we
delegate to the existing stack unwinding mechanism to deal with multiple
activations interspersed with non-interpreter stack frames on the actual
machine stack.

4b9eb7f711 [runtime] Better instance pre-sizing with transpiled classes.
For instances created via constructors and `new` we try to pre-size
the instances such that ideally all the data properties can be
allocated as in-object properties (and we don't need to allocate the
out-of-object PropertyArray backing store). This is accomplished with
the helper of the Parser, which counts the property assignments to
`this` in the constructor, and we use that as the starting point for
pre-sizing logic (a mechanism called *slack tracking* is used to
dynamically shrink the objects based on the real memory usage, and
eventually compute the final starting size for instances of the
individual constructors).

This works well even with class hierarchies, since for a derived class
constructor we just include the current constructor plus all the base
constructors. I.e. with

```js
class A {
  constructor() {
    this.x00 = null;
    this.x01 = null;
    this.x02 = null;
    this.x03 = null;
    this.x04 = null;
    this.x05 = null;
    this.x06 = null;
    this.x07 = null;
    this.x08 = null;
    this.x09 = null;
    this.x10 = null;
    this.x11 = null;
    this.x12 = null;
    this.x13 = null;
    this.x14 = null;
    this.x15 = null;
    this.x16 = null;
    this.x17 = null;
    this.x18 = null;
    this.x19 = null;
  }
}

class B extends A {
  constructor() {
    super();
  }
}
```

we will eventually learn that instances of `B` need 20 in-object
properties. However this breaks with transpiled code (i.e. as
generated via TypeScript or Babel), even when the constructors are
properly chained.

```js
function A() {
  this.x00 = null;
  this.x01 = null;
  this.x02 = null;
  this.x03 = null;
  this.x04 = null;
  this.x05 = null;
  this.x06 = null;
  this.x07 = null;
  this.x08 = null;
  this.x09 = null;
  this.x10 = null;
  this.x11 = null;
  this.x12 = null;
  this.x13 = null;
  this.x14 = null;
  this.x15 = null;
  this.x16 = null;
  this.x17 = null;
  this.x18 = null;
  this.x19 = null;
}

function B() {
  A.call(this);
}
Object.setPrototypeOf(B, A);
```

Here we will always have 10 in-object properties for instances of
`B` (due to the generic over-allocation logic), and the other 10
properties have to be allocated in the out-of-object PropertyArray.

This is unfortunate and actually not necessary. Instead we could just
do the same [[Prototype]] walk on the constructor for regular function
constructors that we perform for derived (native) class constructors.
This CL changes that, such that we give the same treatment to transpiled
class that we have for native classes.

3c3233e6f8 [wasm] js module-builder and constants improvements
Changes made to the Wasm module builder:
- Create emit_u64v for emitting a LEB128 that conceptually represent
an 64-bits integer.
- Differentiate toBuffer and toUint8Array for returning respectively
ArrayBuffer and a Uint8Array.
- Moved wasmF32Const and wasmF64Const functions because we can take
advantage of the existing cached conversion buffers. Also, declaring
them in the constants file will collide with the module-builder since
they are loaded in the same scope.
- The byte_view buffer (used by some conversions to bytes) switched from
Int8Array to Uint8Array.

Changes made to the Wasm contants:
- Add a new kSharedHasMaximumFlag flag for shared memory with a maximum
value.

866d43e6c6 [wasm] Fix interpreter exception stack height change.
This fixes how the interpreter modifies the operand stack in the case
calls with non-zero parameter or return count throw an exception. The
interpreter raises the exception before arguments are popped and before
results are pushed onto the stack. This makes the control transfer
analysis fit this model. It also makes the tests trigger this aspect.

b645a259bd [parser] Allow try {} catch (e) { for (var e of x) {} }
This patch changes the parser to allow for-of initializer
var-redeclaration of non-destructured catch parameters.

Previously, the spec allowed var-redeclaration of a
non-destructured catch parameter…

    try {} catch (e) { var e; }

…except in the particular case where the var declaration is
a for-of initializer:

    try {} catch (e) { for (var e of whatever) {} }

https://github.com/tc39/ecma262/pull/1393 removes this strange
exceptional case. This patch implements that change.

76c9368593 [api, global-handles] Add TracedGlobal
TracedGlobal integrates with the use case of EmbedderHeapTracer and replaces
regular weak Global or Persistent nodes for such cases. This allows to simplify
the case for regular weak handles in a sense that they follow regular weak
semantics (if the underlying object is otherwise unreachable the weak handle
will be reset).

TracedGlobal requires slightly different semantics in the sense that it can be
required to keep them alive on Scavenge garbage collections because there's a
transitive path that is only known when using the EmbedderHeapTracer.
TracedGlobal accomodates that use case.

TracedGlobal follows move semantics and can thus be used in regular std
containers without wrapping data structure.

The internal state uses 20% less memory and allows for only iterating those
nodes when necessary. The design trades the virtual call when iterating
interesting persistents in the GC prologue with calling out through the
EmbedderHeapTracer for each node which is also a virtual call. There is one less
iteration over the set of handles required though and the design is robust
against recursive GCs that mutate the embedder state during the prologue
callback.
