ac6ed35a31 Reland "[async-iteration] implement spec-change to yield in async generators"
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).

ee15703e6c [parser] Prohibit async functions and generators in invalid contexts
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.

1769f892ce [cleanup] Remove always-off support for tail calls
The tail call implementation is hidden behind the --harmony-tailcalls
flag, which is off-by-default (and has been unstaged since February).
It is known to be broken in a variety of cases, including clusterfuzz
security issues (see sample Chromium issues below). To avoid letting
the implementation bitrot further on trunk, this patch removes it.

2bb21e169a resolvedTimezone for Etc/UTC should be UTC per Ecma 402
http://unicode.org/cldr/trac/ticket/9943 added a new separate timezone
ID (Etc/UTC) distinct from "Etc/GMT" even though their behavior is
identical. This CLDR change led v8 to violate Ecma 402 requirement that
resolvedOptions().timeZone for DateTimeFormat be "UTC" for "Etc/UTC"
, "Etc/GMT", "GMT" and "UTC".

This CL made v8 compliant to Ecma 402 again.

2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and 
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

7b300ba2e9 [SAB] Validate index before value conversion using ToIndex
It's required by the spec -- and observable -- that the index be validated
before the conversion of the value(s) via ToInteger.

The previous implementation also had an old test for validating the atomic
index, which has now been switched to ToIndex.

This also exposed an issue in the ia32 code generator: cmpxchg_b requires a
byte register, but the ia32 instruction selector was ensuring that the
new_value was a byte register, not the TempRegister. This change forces the
temp register to use edx, which always can be used as a byte register (dl).
This is the same behavior as currently used in UseByteRegister.

Just swaps the order that properties are loaded from an iterator result
object in the various Async-from-Sync Iterator methods.

Fixes for the test262 tests have been submitted already (https://github.com/tc39/test262/pull/961).

38c5394ccb [intl] Fix NumberFormat options handling spec compliance issues
The goal of this patch was to refactor NumberFormat parameter handling
to be usable by a PluralRules implementation. Along the way, I found
and fixed a couple minor issues where options handling differed from
the specification, and removed some dead code. Regression tests are
added as test262 tests. With this change, the overall flow more closely
resembles the specification plus this editorial change which is out
for review: https://github.com/tc39/ecma402/pull/130/files

bf463c4dc0 [async-iteration] implement AsyncGenerator
- Introduce new struct AsyncGeneratorRequest, which holds
  information pertinent to resuming execution of an
  AsyncGenerator, such as the Promise associated with the async
  generator request. It is intended to be used as a singly
  linked list, and holds a pointer to the next item in te queue.

- Introduce JSAsyncGeneratorObject (subclass of
  JSGeneratorObject), which includes several new internal fields
  (`queue` which contains a singly linked list of
  AsyncGeneratorRequest objects, and `await_input` which
  contains the sent value from an Await expression (This is
  necessary to prevent function.sent (used by yield*) from
  having the sent value observably overwritten during
  execution).

- Modify SuspendGenerator to accept a set of Flags, which
  indicate whether the suspend is for a Yield or Await, and
  whether it takes place on an async generator or ES6
  generator.

- Introduce interpreter intrinsics and TF intrinsic lowering for
  accessing the await input of an async generator

- Modify the JSGeneratorStore operator to understand whether or
  not it's suspending for a normal yield, or an AsyncGenerator
  Await. This ensures appropriate registers are stored.

- Add versions of ResumeGeneratorTrampoline which store the
  input value in a different field depending on wether it's an
  AsyncGenerator Await resume, or an ordinary resume. Also modifies
  whether debug code will assert that the generator object is a
  JSGeneratorObject or a JSAsyncGeneratorObject depending on the
  resume type.
