a3bce19868 Generate StoreGlobal stubs with Hydrogen 
- Constants globals are inlined into Hydrogen code using code dependencies that invalidate the Crankshafted code when global PropertyCells or the global object change.
- The more general case generates code that is just as good as the hand-written assembly stubs on all platforms.

83519ec87a Hydrogen array constructor cleanup and improvements 
* Cleanup of LCallNewArray::PrintDataTo() method
* Created HCallNewArray::PrintDataTo()
* Created many more tests in array-constructor-feedback.js
* Removed redundant instructions in
  GenerateRecordCallTarget
* Bugfix in CreateArrayDispatchOneArgument: on a call to
  new Array(0), we'd like to set the type feedback cell to
  a packed elements kind, but we shouldn't do it if the
  cell contains the megamorphic sentinel.
* When used from crankshaft, ArrayConstructorStubs can
  avoid verifying that the function being called is the
  array function from the current native context, relying
  instead on the fact that crankshaft issues an
  HCheckFunction to protect the constructor call. (this
  new minor key is used in LCodeGen::DoCallNewArray(), and
  influences code generation in
  CodeStubGraphBuilderBase::BuildArrayConstructor()).
* Optimization: the array constructor specialized for
  FAST_SMI_ELEMENTS can save some instructions by looking
  up the correct map on the passed in constructor, rather
  than indexing into the array of cached maps per element
  kind.

6aed526733 The check for internalized strings relied on the fact that we had less 
than 64 distinct InstanceTypes. We are hitting that boundary, so this
check needs to be more comprehensive. In fact, two bits need to be
tested: verify that kNotStringTag isn't set, and that kInternalizedTag
is set.

bcf5912b3f Reduce the amount of full code generated to fill out array literals. 
This is achieved by tuning the calling convention of StoreArrayLiteralStub:

 * The map of the array literal can be loaded in the stub from the
   array literal itself, there is no need to pass it at all.

 * The array literal is already on the stack, so there is no need to
   pass it again via a register.

 * The literal index is unchanged while filling the literal, so we can
   push it on the stack once and avoid passing it every time. Note that
   we need to mirror this change in the stack layout in crankshaft, too.

8a02fd3be3 Turn off allocation site info for crankshafted array constructor calls. 
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

f8db2414f2 Deprecate FACTORY helper macro. 
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

7aa74c3dc5 fix some names in compare nil ic 
The compare nil ic introduces a mechanism called lightweight miss. The
idea is to insert a direct call to the miss handler instead of going
through the deopt routine. This can be use for uninitialized stubs, to
directly jump to the runtime.

This cl
1. Cleans up naming
2. localizes the lightweight miss functionality on the only user (compare nil ic)
3. fixes DoCodegen, to actually call the correct method (uninitialized vs initialized)

e4c957eff6 Accurate function prototypes for native calls from ARM simulator. 
Native method invocation from the arm/simulator-arm.cc previously made
non-portable assumptions about calling conventions. This was okay for 32-bit
stack-based machines, where by-value structs are automatically materialized
on the stack, and where both int and double parameters could be passed on the
stack. However they are not okay for x86-64, which has an elaborate scheme
for passing parameters in registers.

This CL replaces the previous non-portable code paths with portable code,
using call-sites that accurately match the prototype of the callee.

5c93b18eb2 ES6 symbols: Allow symbols as property names 
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).

Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

090d09d685 ES6 symbols: Implement Symbol intrinsic and basic functionality 
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base, 
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

529f801fde Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, 
we store an AllocationSiteInfo object right after the JSArray, with a pointer to the
boilerplate object. Later, if the array transitions we check for the continued existence
of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to
transition the boilerplate array as well.

4246ac3009 Generalize calling to C++ on stub deopt 
Remove code specific to KeyedLoadICs in DoCompiledStubFrame on all platforms, driving stub frame translation by the register parameter information found in a stub's CodeStubInterfaceDescriptor.

bb96439743 Cleanup RelocInfo::NONE usage. 
There are now NONE and NONE64 RelocInfo types, but only ARM uses them
both at the same time. They were added in:
  https://chromiumcodereview.appspot.com/11191029/

I'll rename NONE to NONE32 in a later CL.

This CL cleans up the RelocInfo::NONE usage by:
 - Using RelocInfo::IsNone when testing for NONE-ness.
 - Using NONE on 32-bit platforms (MIPS and IA32), and NONE64 on 64-bit
   platforms (x64).

This cleans up the code and prevents it from evolving bugs in the future
because NONE32 and NONE64 are used in misleading ways.

17326e8746 Refactor and improve inlined double-aligned allocations 
Change is performance neutral but generates smaller code and encapsulates double alignment in the macro-assembler rather than at the allocation site.
