ef21fb2de6 [Interpreter] Ensure we always have an outer register allocation scope.
Split RegisterAllocationScope out of ExpressionResult and allocate one
for each statement. This ensures that we always have an outer register
allocation scope for statement code (used in CountOperation and
RegisterExecutionResult). Also refactored the register allocator code to
move it to it's own file and rename from TemporaryRegisterScope to
BytecodeRegisterAllocator.

41719a42ac Restrict GeneratePreagedPrologue to proper functions.
This solves a bug discovered with fast accessors, where a pre-age prologue
was written into a stub. Since StaticMarkingVisitor<.>::IsFlushable will
only flush Code::FUNCTION [1], we'll restrict GeneratePreagedPrologue to
functions, too, instead of adding a Code::STUB restriction.

Also, generalize api accessor test cases to --optimize-for-size.
Also, fix CompilationCacheCachingBehavior for --optimize-for-size.

eccbdde041 [Interpreter] Removes assignment hazard scope.
Removes assignment hazard scope. Reverts back to the naive scheme of
allocating a temporary for every variable load. It was decided to revert it
because the current implementation does not handle logical expressions,
ternary operators, visiting objects in named/keyed loads. Also, we wanted
to evaluate alternate approaches and choose one when we have a mechanism
to measure performance.

ed21aa2449 [turbofan] Avoid using the typer's types in representation inference for phis.
Once we use type feedback, we need to reflect the feedback in the types, propagate
the new narrower types forward and use them in the subsequent
representation inference. This CL propagates and uses the recomputed types
for Phi and Select nodes (rather than using the types from the typer).

322ffda30d [builtins] Migrate Number constructor similar to String constructor.
Also migrate the Number constructor to a native builtin, using the
same mechanism already used by the String constructor. Otherwise just
parsing and compiling the Number constructor to optimized code already
eats 2ms on desktop for no good reason, and the resulting optimized
code is not even close to awesome.

Drive-by-fix: Use correct context for the [[Construct]] case of the
String constructor as well, and share some code with it.

f5828cb4db Stop treating scopes containing template strings tagged with 'eval' specially
There's no need to mark these as possibly-direct-eval, since all such an
eval-tagged string will ever get passed is the array of string parts, which
will be immediately returns (since it's not a string). It will
never do a lookup in the current scope, nor (in sloppy mode) introduce
new declarations.

This patch is not intended to change behavior, but I've added tests that
demonstrate the stuff explained in the preceding paragraph.

569145019d Add @@species/better subclassing support to Promises
This patch makes Promise.prototype.then use @@species as specified
in ES2015. The fix is hoped for by certain users, such as legacy
core.js versions which encounter an unhandled Promise reject (complete
with an ugly console message) when Promise subclassing is supported
in a mostly correct way, and we do error checking on Promise
constructors, but @@species is not supported.

2bd9bdbe62 TypedArray and ArrayBuffer support for @@species
This patch improves ArrayBuffer and TypedArray subclassing by adding
support for @@species and constructing outputs to certain methods
by creating an instance of the constructor determined by the
SpeciesConstructor algorithm, rather than fixed to a superclass or
naively the constructor. The new behavior is enabled by the
--harmony-species flag. Care is taken to not significantly change the
observable behavior when the flag is off. Previously, TypedArrays
already supported subclassing by reading the constructor of the
receiver, but ArrayBuffers did not, and this old behavior is
preserved and tested for, to avoid a multi-stage upgrade path and keep
things simple for users.

95145fa826 Ship ES2015 sloppy-mode const semantics
This patch moves the semantics of 'const' in sloppy mode to match those
in strict mode, that is, const makes lexical (let-like) bindings, must
have an initializer, and does not create properties of the global object.

ee9d7acafc Partial rollback of Promise error checking
As V8 becomes more and more spec-compliant, Promise polyfill libraries
like core.js expect fully correct. However, our Promises do not yet
support Symbol.species. Therefore, a case like

```
var test = new Promise(function(){});
test.constructor = function(){};
Promise.resolve(test)
```

would lead to an unhandled Promise rejection, whereas it should not
because test.constructor[Symbol.species] is undefined, so test.then
should end up constructing %Promise% as a fallback, rather than
calling test.constructor as if it were a constructor, which leads
this error checking code to throw.

For now, this patch removes the error checking code (which was not
present until recently). In an interactive test using core.js, the
error message on the console goes away with this patch. When @@species
support is in place, this patch can be reverted. A regression test
is added which checks for the same thing.

Partially reverted patch was originally out for review at

eb9deba815 Fix sloppy block-scoped function hoisting with nested zones
The sloppy block-scoped function declaration placeholder statements
are held in parser_zone_-allocated hashtables. These hashtables are
not updated when local_zone_s are removed. Therefore, the
NewSloppyBlockFunctionStatement method should allocate
SloppyBlockScopeFunctionStatements in the parser_zone_ to avoid a
use-after-free. Scope fixup code may end up updating something which
is thrown away, but this is a small cost and much simpler than
removing dead hashtable entries later.

0427d9ff2a WASM: Reserve an ignored section for source code meta information.
Requesting reservation of a wasm section for experimentation with
storing source code meta information, such as source code comments,
and also extra inform on presentation of the AST such an `if-block`
pattern being presented as a `when` operation.

The wasm design already defines unrecognized sections to be ignored,
and this reserved section is ignored. This section is only intended to
hold source code meta information and to have no effect on code
execution.

With wasm going live (behind a flag) on v8, I would also like to be
able to give people something to play with in terms of the deployed
binary code being a useful source code. It's all experimental, but I
understand the entire binary format that V8 is currently using is
basically a throwaway, and that the working strategy is to get
something running and then revisit format decisions.

I would like a fixed reserved section number to avoid potential
clashes with other projects - although I am not aware of any other
calls for addition sections beyond the need for debug info. If a fixed
number is not acceptable, then could this patch alternatively ignore
all unrecognized sections and perhaps add the section size to them
all - something which is already noted todo in the design document?

7459d8cecb [promise] Make Promise.all match spec, and always respect [[AlreadyResolved]]
Testing the promise status is not enough to ensure that resolve functions are
called only once.

This change adds a similar version of the [[AlreadyResolved]] slot to the
Promise.all resolve element function, and also ensures that [[AlreadyResolved]]
is respected in the Promise executor, and when resolving thenables. This means
replacing PromiseReject() shortcuts with promiseCapability.reject(), which has
an [[AlreadyResolved]] record in a context slot.

Also ensures that changes to the list accumulator in Promise.all() is not observable
via accessors installed in the Array prototype chain, using the same mechanism used
in several Array methods.

Fixes the following Test262 tests:
- built-ins/Promise/all/call-resolve-element-items.js

6e96223750 Add Array support for @@species and subclassing
This patch implements @@species, guarded behind the --harmony-species
flag, on Arrays. Methods which return an Array will instead return
the appropriate instance based on the ArraySpeciesCreate algorithm.
The algorithm is implemented in C++ to get access to realm information
and to implement some Array methods in C++, but it is also accessed
from JavaScript through a new runtime function. A couple interactive
Octane runs show no performance regression with the flag turned off,
but turning --harmony-species on will surely have a significant
regression, as Array methods now heavily use ObjectDefineProperty.

48bc94253f X87: [wasm] Change the test case for Run_WasmCall_Float32Sub
The reason is same as the CL #31808 (issue 1430943002, X87: Change the test case for X87 float operations), please refer: https://codereview.chromium.org/1430943002/

  Here is the key comments from CL #31808
  Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined functions has different behavior comparing with GCC ia32 build and x87 build.
  The major difference is sse float register still has single precision rounding semantic. While X87 register has no such rounding precsion semantic when directly use register value.
  The V8 turbofan JITTed has exactly same result in both X87 and IA32 port.

  So we add the following sentence to do type case to keep the same precision for Run_WasmCall_Float32Sub.
  Such as: volatile float expect = *i +/- *j; // *i +/- *j, etc.

2367abf025 [es6] Handle function names in object and class literals
This required refactoring ParsePropertyDefinition to pass the parsed
string name as an out param, since ObjectLiteralProperty stores Smis
for Smi-representable property keys.

Computed properties are not yet handled in this patch.

fcff8588a5 Ship ES2015 sloppy-mode function hoisting, let, class
This patch doesn't ship all features of ES2015 variable/scoping
changes, notably omitting the removal of legacy const. I think
function hoisting, let and class in sloppy mode can stand to
themselves as a package, and the legacy const change is much
riskier and more likely to be reverted, so my intention is to
pursue those as a separate, follow-on patch.

e4af5cdbf9 [promise] Make Promise.reject match spec, and validate promise capabilities
Correctly validate promise capabilities in NewPromiseCapabilities() and in
GetCapabilitiesExtractor(). Also explicitly follows Promise.race step 2 and
similar cases in the spec, rather than passing tests asserting these steps
are taken in NewPromiseCapability

Also changes Promise.reject to match specification.

Fixes the following test262 tests:

- built-ins/Promise/all/capability-executor-called-twice.js
- built-ins/Promise/all/capability-executor-not-callable.js
- built-ins/Promise/prototype/then/capability-executor-called-twice.js
- built-ins/Promise/prototype/then/capability-executor-not-callable.js
- built-ins/Promise/reject/capability-executor-called-twice.js
- built-ins/Promise/reject/capability-executor-not-callable.js
- built-ins/Promise/resolve/capability-executor-called-twice.js
- built-ins/Promise/resolve/capability-executor-not-callable.js
- built-ins/Promise/race/capability-executor-called-twice.js
- built-ins/Promise/race/capability-executor-not-callable.js
- built-ins/Promise/reject/S25.4.4.4_A3.1_T1.js
- built-ins/Promise/race/S25.4.4.3_A3.1_T2.js

Per v8:3641, mjsunit/es6/debug-promises/throw-with-undefined-reject.js becomes invalid. The exception is thrown before the chain handler is ever invoked, and is caught externally by d8's own handler --- thus evading the uncaught exception event.
