When storing an indexed property in a typed array, it's necessary to
convert the value to a Number (or to a Bigint) before performing the
bounds check, per
https://tc39.github.io/ecma262/#sec-integerindexedelementset.
This CL adds appropriate type conversions in
Object::SetPropertyInternal (which technically is reached after the
bounds check has already occurred, but this isn't observable yet ---
In the future, once OOB accesses on TypedArrays actually throw, this
will need to be refactored again), and in StoreFastElementStub, and
ElementsTransitionAndStoreStub (via CSA::EmitElementStore).
The change was not necessary in TurboFan, as
JSNativeContextSpecialization already performs the value conversion
before the boundscheck.
The result is some fixed test262 tests, and some new test coverage
for this behaviour in mjsunit.

This is a reland of 91bab5588c
This CL contains two major changes w.r.t to the original CL:
The random state is removed from the Smi root list and we pre-seed the RNG
on each sort with the length of the array.
To cut down on the length of the arguments list and to keep track of the
random state across recursive calls, we move most of the sort arguments into
a FixedArray and reload from the array for each recursion.

Not all 2 or 3 letter language codes are canonical. Some of them need
to be canonicalized.
Specifically, exclude {jw,ji,iw,in} and all three-letter codes from the
fast path except for 'fil'.
{jw,ji,iw,in} are deprecated ISO 639 codes for
{Javanese, Yiddish, Hebrew, Indonesian}. They should be
canonicalized to {jv,yi,he,id}. So, do not return early
in the fast path, but pass it down to the full canonicalization.
In addition, there are 70+ deprecated 3-letter codes that need to be
replaced by their modern equivalents. Instead of checking and replacing
in v8, just pass them to ICU to handle.
Along with the following ICU change, two more tests will pass.
https://chromium-review.googlesource.com/c/chromium/deps/icu/+/1026797
These two tests still fail because of the disagreement between ICU and the test

This CL implements TypedArray.p.sort in Torque. The Torque
version works basically the same as the existing JS builtin:
When no comparison function is provided, the C++ fast path builtin
is used. Otherwise a quicksort written in Torque is used, with
a InsertionSort fallback for smaller arrays.
The JS quicksort implementation also containes a more elaborate
third pivot calculation for larger arrays. This is currently not done.
Reported benchmark results are only for those, where a custom
comparison function is provided. The numbers for the C++ path stayed
the same.

Implements the change outlined in https://github.com/tc39/ecma262/pull/890,
which has been ratified and pulled into the specification. In particular,
template callsite objects are no longer kept in a global, eternal Map, but
are instead associated with their callsite, which can be collected. This
prevents a memory leak incurred by TaggedTemplate calls.
Changes, summarized:
- Remove the TemplateMap and TemplateMapShape objects, instead caching
template objects in the feedback vector.
- Remove the `hash` member of TemplateObjectDescriptor, and the Equals
method (used by TemplateMap)
- Add a new FeedbackSlotKind (kTemplateObject), which behaves similarly
to FeedbackSlotKind::kLiteral, but prevents eval caching. This ensures
that a new feedback vector is always created for eval() containing tagged
templates, even when the CompilationCache is used.
- GetTemplateObject bytecode now takes a feedback index, and only calls
into the runtime if the feedback is Smi::kZero (uninitialized).

This change does not modify generated bytecode (but maybe it should to
take advantage of load IC feedback for loading "next"). Doing this grows
bytecode by quite a bit, since it's necessary to throw-if-not-an-object

instead).

https://github.com/tc39/ecma262/pull/988 gained concensus during the
september 2017 TC39 meetings. This moves the load of the "next" method
to the very beginning of the iteration protocol, rather than during
each iteration step.
This impacts:
- yield*
- for-of loops
- spread arguments
- array spreads
In the v8 implementation, this also affects async iteration versions of
these things (the sole exception being the Async-From-Sync iterator,
which requires a few more changes to work with this, likely done in a
followup patch).
This change introduces a new AST node, ResolvedProperty, which can be used
as a callee by Call nodes to produce the same bytecode as Property calls,
without observably re-loading the property. This is used in several
AST-desugarings involving the iteration protocol.

Keeping expected outcomes inside output processors should be
optimized in the future. Few possible optimizations:
- separate classes for tests that are expected to PASS - done as
an example in mozilla test suite.
- cache output processors inside testcase.
- share output processors between copies of the same test - needs

1. Getting outcomes - reads both variant dependent and
independent outcomes, no more need to do it twice.
2. Checking unused rules - has a switch to check only variant
dependent/independent rules.
3. Reading flags - if outcome starts with '--' it is treated as a flag.
4. Actual filtering.
Outcomes removed from the testcase object, can be accessed
by call to its testsuite.

The DEPS roll in f3a2e34d updated ICU to a version that includes
a fix for https://ssl.icu-project.org/trac/ticket/13462. As a
result, our Script_Extension data is now correct again.
This patch re-enables the Test262 tests that were failing due to this

Per https://github.com/tc39/proposal-async-iteration/pull/102/files:
AsyncGeneratorResolve no longer unwraps a value component. Instead, the value is
unwrapped before the builtin call via Await, allowing Promise rejections to
affect the generator control flow.
Thus, all `yield <expr>` implicitly become `yield await <expr>`.
Additionally, `return <expr>` becomes `return await <expr>`. Finally, when the
generator is resumed with `.return()`, the parameter passed to .return() is
awaited before generator execution properly continues).

Async functions and generator declarations are only permitted as
StatementListItems, not as ExpressionStatements, and therefore not
as the entire body of an if statement, etc. Previously, they were
incorrectly permitted. However, ChakraCore and SpiderMonkey seem
to ban them in this context, and the feature was introduced relatively
recently, so it is likely to be web-compatible to ship the prohibition.
This patch also unifies the error message wording of async functions
and generators to ordinary functions, explaining more clearly what
the issue is.
