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.

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).

598e2f9fc0 X87: Start using OStreams. 
port r22179

original commit message:

Note that until everything is OStream-based, there are a few places
where we have to do some impedance matching. A few accessors had to be
const-corrected on the way.

40af47d46a [Arm]: Enable use of extended out-of-line constant pool for Arm. 
- Adds support to the Arm assembler to use extended constant pools.
 - Update (set_)target_address_at to support extended constant pool load
   updates.
 - Replace Operand::is_single_instruction with Operand::instructions_required
   Due to the fact that different constant pool load types require different
   numbers of instructions.
 - Various cleanups of ConstantPoolBuilder to cleaner integration of the
   extended constant pool building.
 - Update GetRelocatedValue such that offsets to both map_check and bool_load
   are explicitly provided, rather than location of bool_load being inferred
   based on map_check, since the code inbetween is no longer of a predictable
   size.
 - Update MacroAssembler::GetRelocatedValueLocation() to add support for
   getting a value from an extended constant pool entry.
 - Update Debug::SetAfterBreakTarget() to use target_address_from_return_address
   when checking for debug breaks at constant pool load points.
 - Change ConstantPoolIterateBody to iterate over both heap and code pointer in
   the small section before moving onto the extended section, to work around the
   requirement of the serializer that pointers are iterated in-order.
 - Increase old_pointer_space SizeOfFirstPage() to offset the fact that constant
   pools are now in the old pointer space (rather than code).

5baaf3c981 Use the HeapObjectIterator to scan-on-scavenge map pages. 
Deserializing the partial snapshot may prematurely stop using a map page, adding a free-space filler at the end. Scan-on-scavenge of map-space did not expect anything but maps, and would interpret the uninitialized memory as pointers. Using the heap iterator we can skip over free space and only visit maps.

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).

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.

6ff2a77364 Wrap InitializeProperty around SetOwnPropertyIgnoreAttributes and switch over uses 
This is a step in the direction of disentangling all uses of SetOwnPropertyIgnoreAttributes so we can provide a more specific implementation for those usecases, and reduce the capabilities of those clients, avoiding subtle bugs.

InitializeProperty only supports adding properties to extensible objects that do not contain the property yet. JSGlobalProxies cannot have properties themselves, so are not supported either.

7aa8cb462f [Arm]: Make Assembler::movw only emit a movw instruction. 
Currently Assembler::movw is really the mov macro instruction, leading to raw
emit calls to generate the real movw instruction. Replace all calls of mow
with the mov macro instruction (which will emit a movw if appropriate) and
make movw always emit movw.

c1e6743739 [Arm]: Fix liveedit support if --enable_ool_constant_pool is true. 
If the out of line constant pool is enabled, there is an extra value on the stack frame (the
constant pool pointer).  This change fixes GenerateFrameDropperLiveEdit to pull the function
pointer and pop the stack frame correctly whether or not the constant pool pointer is on the
frame.

8ff53a8d62 X87: The IC exposes a register definition. 
port r22011

original commit message:
  Centralize a register definition in an IC that provides:
  1) symbolic names for the register (like, edx == receiver)
  2) defines ordering when passed on the stack

  Code that implements or uses the IC should use this definition instead of "knowing" what the registers are. Or at least have the definition to validate it's assumptions.

  As a side effect of avoiding runtime static initializers (enforced by tools/check-static-initializers.sh, neat), I gave ownership of the registers array to CodeStubInterfaceDescriptor. This prompted a cleanup of that struct

55126885b7 MIPS: The IC exposes a register definition. 
Port r22011 (be22370)

Original commit message:
Centralize a register definition in an IC that provides:
1) symbolic names for the register (like, edx == receiver)
2) defines ordering when passed on the stack

Code that implements or uses the IC should use this definition instead of "knowing" what the registers are. Or at least have the definition to validate it's assumptions.

As a side effect of avoiding runtime static initializers (enforced by tools/check-static-initializers.sh, neat), I gave ownership of the registers array to CodeStubInterfaceDescriptor. This prompted a cleanup of that struct.
