9e121d0d5d Remove unused variables from assembler-arm.cc. 
Local arm.debug build with make fails - not sure why arm build doesn't fail on
the waterfall.

63b3d1358c ARM: Fix inline assembly (r21949) for Clang. 
Add a 'c' predicate to the immediate syscall number. This tells the
compiler to omit the leading '#' that immediates usually have in ARM.
The GNU assembler tolerates "ldr r7, =#1234" but Clang does not.

6b264de751 ARM: Clean up FlushICache. 
In theory, the Thumb version of FlushICache doesn't have to be any
different from the ARM version: There is no need to switch to ARM mode
for the svc, and r7 can be used just like any other register.

In practice, GCC uses r7 as a frame pointer in Thumb code, and it
refuses to allow it be used in inline assembly. To avoid complicated
checks to determine whether or not it is possible to use it directly,
the FlushICache function explicitly preserves r7.

b3f8487726 Create a RegisterSpec class inside of the IC that provides: 
1) symbolic names for the register (like, edx == receiver)
2) can return an array of registers
3) defines ordering when passed on the stack

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

7f429e62c3 [Arm]: Simplify compile-time Arm feature detection. 
Simplify the compile time feature detection on Arm:
 - Define CAN_USE_XXX definitions unconditionally for all target/host
   toolchain combinations
 - Rename arm_test / ARM_TEST to arm_test_noprob / ARM_TEST_NO_FEATURE_PROBE
 - Don't set ARM_TEST_NO_FEATURE_PROBE implicitly on the simulator to make
   make simulator / native more consistent
 - Unify CpuFeatures::PrintTarget for simulator and native builds
 - Remove unecessary CAN_USE_VFP_INSTRUCTIONS definition for android (this is
   the default for arm_fpu=default)
 - Add a CpuFeatures::Probe() before calling CpuFeatures::PrintFeatures() in PrintHelp
    to ensure we have probed features before printing them.

 - Do calculation of the target address of a load from constant pool in one

736a17f8f4 ARM: Avoid duplicate vmla when merging vmul and vadd 
Avoid generating duplicate vmla instructions for vmul/vadd sequences where the
vmul has more than one use.

For example: function f(a, b, c) { return (a * b) + c + (a * b); }

Previously, this would produce a vmul for the subexpression (a * b), then vmla
for (a * b) + c, then vmla for (a * b) + [(a * b) + c].

Now it produces vmul, vadd, vadd, as expected.

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.

b09989ec58 Refactor transitioning stores. 
There's actually no need to have the transition as part of the HStoreNamedField instruction. In fact, it is cleaner and faster to generate a separate HStoreNamedField for the transition map. This will also help to eliminate map stores with store elimination, as well as reduce register pressure for transitioning stores on ia32.

63199d0bfe Avoid flushing the icache unnecessarily when updating target addresses in code. 
This CL updates RelocInfo update operations and set_target_address_at to enable
skipping of the icache flush if it going to be batched up later.
Code::CopyFrom and Code::Relocate are modified to avoid individual icache
flushes since the whole code area will be flushed after the reloc info is
updated.

These changes reduce a regression when enabling the OOL constant pool on Arm,
since this change can cause MovT/MovW instructions for relocatable targets
if the constant pool is full.

Scores for Mandreel latency on a Nexus 5:
 - OOL CP disabled: 3533
 - OOL CP enabled, without this CL: 1825
 - OOL CP enabled, with change: 3015

Traditionally, we cross compile a snapshot iff the serializer is enabled.
This will change in the future.

Changes:
 - CpuFeatures probing is done once per process, depending on whether we
   cross compile.
 - CpuFeatures are consolidated into the platform-independent assembler.h
   as much as possible.
 - FLAG_enable_<feature> will only be checked at probing time (already the
   case for ARM).
 - The serializer state is cached by the MacroAssembler.
 - PlatformFeatureScope is no longer necessary.
 - CPUFeature enum values no longer map to CPUID bit fields.

Fix for divisor=1, found during code inspection. We can't hit this bug, due to
HDiv::Canonicalize() discarding the operation, but it might avoid a future bug

71789ea1e5 Reland r20974: Unify and simplify the FastCloneShallowArrayStub 
- Don't bake in length/capacity into full codegen calls of stubs,
allowing boilerplates to increase their capacity without regenerating
code.
- Unify all variants of the clone stub into a single,
length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

5170a008d3 Generation of our home-grown memmove doesn't depend on serializer state anymore. 
The serializer state has to be per-Isolate, but at the point where we
generate our memmoves we don't really have an Isolate. Furthermore,
there was no fundamental reason why we shouldn't use our home-grown
memmove during mksnapshot time.

Perhaps we can totally remove our own memmove nowadays, but this would
be a separate CL.

code generation phase instead, which is always run on the

198c4769f2 Unify and simplify the FastCloneShallowArrayStub 
- Don't bake in length/capacity into full codegen calls of stubs,
  allowing boilerplates to increase their capacity without regenerating
  code.
- Unify all variants of the clone stub into a single,
  length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
  therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

dd30db9021 CodeStubs contain their corresponding Isolate* now. (part 1) 
This is a purely mechanical change, adding an Isolate* to the CodeStub
constructor and a corresponding field plus a getter. A few methods in
CodeStub and its subclasses can be simplified now, but this is done in
a separate CL.

The underlying reason apart from simplicity is that deep down in the
call chain we need to detect if the serializer is active or not. This
information will be part of the Isolate, not a global variable with
funky synchronization primitives around it (which is fundamentally
wrong and the underlying cause for race conditions and a catch-22
during initialization).

3308cb5857 ES6: Add support for Map/Set forEach 
This implements MapIterator and SetIterator which matches
the same constructs in the ES6 spec. However, these 2
iterators are not exposed to user code yet. They are only
used internally to implement Map.prototype.forEach and
Set.prototype.forEach.

Each iterator has a reference to the OrderedHashTable where
it directly accesses the hash table's entries.

The OrderedHashTable has a reference to the newest iterator
and each iterator has a reference to the next and previous
iterator, effectively creating a double linked list.

When the OrderedHashTable is mutated (or replaced) all the
iterators are updated.

When the iterator iterates passed the end of the data table
it closes itself. Closed iterators no longer have a
reference to the OrderedHashTable and they are removed from
the double linked list. In the case of Map/Set forEach, we
manually call Close on the iterator in case an exception was
thrown so that the iterator never reached the end.

At this point the OrderedHashTable keeps all the non finished
iterators alive but since the only thing we currently expose
is forEach there are no unfinished iterators outside a forEach
call. Once we expose the iterators to user code we will need
to make the references from the OrderedHashTable to the
iterators weak and have some mechanism to close an iterator
when it is garbage collected.
