7367720daa Implement handling of arrow functions in the parser 
Arrow functions are parsed from ParseAssignmentExpression. Handling the
parameter list is done by letting ParseConditionalExpression() parse
a comma-separated list of identifiers, and it returns a tree of
BinaryOperation nodes with VariableProxy leaves, or a single
VariableProxy if there is only one parameter. When the arrow token "=>"
is found, the VariableProxy nodes are passed to ParseFunctionLiteral(),
which will then skip parsing the paramaeter list. This avoids having
to rewind when the arrow is found and restart parsing the parameter
list. Note that ParseExpression() expects parenthesized expressions
to not be empty, so checking for a closing parenthesis is added in
handling the empty parameter list "()" will accept a right-paren and
return an empty expression, which means that the parameter list is
empty.

Additionally, this adds the following machinery:

 - A runtime flag "harmony_arrow_functions" (disabled by default).
   Enabling "harmony" will enable it as well.
 - An IsArrow bit in SharedFunctionInfo, and accessors for it.
 - An IsArrow bit in FunctionLiteral, accessorts for it, and
   a constructor parameter to set its value.
 - In ParserBase: allow_arrow_functions() and set_allow_arrow_functions()
 - A V8 native %FunctionIsArrow(), which is used to skip adding the
   "function " prefix when getting the source code for an arrow
   function.

31134fafef X87: More OStreamsUse OStreams more often 
port r22232

original commit message:

This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

6d5d4b44b5 Remove a bunch of Isolate::UncheckedCurrent calls 
The callbacks are per isolate, so we shouldn't get the isolate implicitly
from TLS. Also, we shouldn't allow calls to these methods prior to
initializing the respective isolate (and silently ignore them).

Esp. add a per-isolate API to set the stats counter callbacks and
make it possible to set the stats counter callback after the isolate
was touched.

Embedders should use e.g. isolate->SetCounterFunction(callback) instead
of v8::V8::SetCounterFunction(callback).

Also remove the "use default platform" compile flag. Instead, the embedder

Change all binaries to use the default platfrom from libplatform.

Unless --job-based-sweeping is passed, nothing uses the platform yet, so
nothing will break for embedders (yet).

Temporarily reverting until we figure out how to handle the API cases that use accessors to lazily compute values.
dataAttributeGetterCustom in V8MessageEventCustom (at least) overwrites itself with the computed value using ForceSet. We can either force such clients to first use ForceDelete before caching, use some other caching mechanism; or provide an API for lazily computed properties.

as an out param.

On the Map ForEach perf test this leads to a 2.5x performance
improvement. On the overall Map and Set tests this leads to a 18%

7b7bb25a24 Support external startup data in V8. 
[Re-retry of r21696 and r21739]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

ba9f391bc0 Support external startup data in V8. 
[Retry of crrev.com/293993021, which caused problems with 'ninja all' in Chromium. First patch set if a clean apply
of crrev.com/293993021. Subsequent sets are the actual fix
for that issue.]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

13d2f365cc Add API support for passing a C++ function as a microtask callback 
This allows embedders to enqueue microtasks without having any v8::Context
handy, as happens in Blink in some cases (such as DOM mutations due to editing
triggering MutationObservers).

97c962c255 Add support for extended constant pool arrays. 
This CL adds support for ConstantPoolArrays which contain an extended section.
This will be used to enable larger constant pools than can be addressed by a
single ldr with immediate offset instruction (which has a limit of a 4KB range).
Extended constant pools will have a small section, which is addressable via a
single ldr instruction, and an extended section, which will require a multi-
instruction sequence to load from.

Currently, no code uses the extended ConstantPoolArray's - this change will
be made in a followup CL.

A number of changes are made to the ConstantPoolArray object in order to
support this:
  - Small section layout is now entirely defined by the small layout bitmaps.
  - The ConstantPoolArray no longer extends FixedArrayBase since the length
    field is not useful for extended layouts.
  - Enums are used to represent the type of an entry and the layout section.
  - An iterator can be used to iterate through all elements of a given type.
  - A number of tests were added for these features.

There were no explicit tests for FuncNameInferrer (though, some tests might
implicitly rely on it working properly in the common cases). Afaics, there were
no tests which would exercise inferring two byte function names or escaped
function names.

61509aaea5 Support external startup data in V8. 
If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

60a71d8a8c Remove PROHIBITS_OVERWRITING as it is subsumed by non-configurable properties. 
v8::DontDelete is set for Unforgeable properties, so just not setting PROHIBITS_OVERWRITING should be enough.

The secondary "feature" of not allowing accessors to be installed in extending objects is incorrect and confusing, given that it only applies to accessors but not to regular properties:
Object.defineProperty({__proto__:window}, "location", { value: 10 })
works where
Object.defineProperty({__proto__:window}, "location", { get: function() {} })
doesn't work.
