It can't just inherit from a FixedTypedArray-like type, as we soon
assume that a FixedTypedArray-like type is always held by an
ArrayBufferView-like type

The embedder has to take appropriate steps to ensure that the
ArrayBuffer doesn't die while it's accessing the pointer, e.g. keep a
Local handle to it around

Implements the strong mode proposal's restrictions on the syntax of the
switch statement. Also fixes a minor bug with empty statements in strong
mode and improves StrongUndefinedArrow parser synch tests.

This fixes a race where
- mutator changes the fixed array length by trimming it,
- sweeper thread reads the length of the fixed array.
Also rename FROM_GC and FROM_MUTATOR to be more precise.

- make ParallelMove into a ZoneVector, removing an annoying level of indirection
- make MoveOperands hold InstructionOperands instead of pointers, so there's no more operand aliasing for moves
- opens up possibility of storing MachineType in allocated operands

Add a finalize incremental marking mode for CollectAllGarbage to finalize incremental marking when incremental marking is in progress, but we want a full gc at a given CollectAllGarbage call site.
Default mode for CollectAllGarbage is finalize incremental marking and perform a full GC.

This avoids both a mysterious boolean argument ("insert") and lets
non-mutating lookups skip passing an allocator (in one such case,
we were passing a scary-looking ZoneAllocationPolicy(NULL)!).

This allows the embedder to decide whether it's worthwhile to copy the
contents to avoid materializing a buffer.

This makes the compilers agree on the source position of a message
generated by "throw new Error()", it points to the beginning of the

When debugging Handle leaks in io.js we found it very convenient to be
able to Seal some specific (root in our case) scope to prevent Handle
allocations in it, and easily find leakage.

Implements the strong mode proposal's static restrictions on the use of the
identifier 'undefined', for arrow functions. Assumes these restrictions are
intended to be identical to the restrictions on the use of 'eval and 'arguments'
in strict mode. In addition, Location variables inconsistantly named (e.g.
dupe_error_loc vs dupe_loc) are now consistently named the shorter way.

Implements the strong mode proposal's static restrictions on the use of the

AllowEvalOrArgumentsAsIdentifier enum has been renamed to
AllowRestrictedIdentifiers as logic involving it is now also used for this case.

These comparisons are only meant to be done by AstValueFactory itself (in
its string_table_ operations), so make the Compare() function a private
member of AstValueFactory.
All other clients of AstRawStrings should compare them by pointer value.
There were only two clients which failed to abide by this rule, one
recently-added (in ModuleDescriptor) and the other in Literal::Match
(in ast.cc, added in https://code.google.com/p/v8/source/detail?r=24396).

- ConstantOperand was using a too-small field too store its virtual register
- drop ConvertTo, replace it with simple copy
- split AllocatedOperand off from Immediate and Constant to make assignment clearer, also paving the way for small Immediates
- put zone first in *Operand::New
- driveby: drop delayed ssa deconstruction experiment
