7d478d9621 Revert of Remove obsolete V8_INFINITY macro. (patchset #3 id:40001 of https://codereview.chromium.org/798413003/) 
Reason for revert:
Speculative revert. This seems to block the current roll: https://codereview.chromium.org/819653003/

I retried several times, also with a new roll. The error is internal - but that doesn't make much of a difference.

71bb00e261 Consistently use only one of virtual/OVERRIDE/FINAL. 
FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use
more than one of these. The Google C++ style guide even requires this, see
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance.

While we're here, port r24662 to x87.

The net result is that v8 compiles again with a current clang.

7384467552 Further improve deopt reason output. 
* Make the detailed deopt reason mandatory on x64, other platforms
  will follow in separate CLs.

* Extracted and improved jump table entry sharing logic: When
  --trace-deopt is on, we get separate entries for different deopt
  reasons. This enables us to distinguish the several reasons single
  instructions can have.

* Don't emit superfluous jump table comments: The bailout ID is still
  visible, and the jump table entry number is not interesting (but
  easy to determine if really needed).

* Unify the internal name of the jump table member across platforms.

80d9d6df30 Thread the Lithium instruction down to DeoptimizeIf and friends. 
This is a purely mechanical refactoring and a first step towards being
able to report more helpful deoptimization reasons. With this
refactoring, we know at least the mnemonic of the instruction causing
the deopt, although this is not used yet. Future steps will be using
the mnemonic, passing additional explicit deopt reasons and removing
the fragile machinery of searching for code comments.

ac1b9b11dc Fixed deopt reasons in TaggedToI. 
Every DeoptimizeIf should be preceded by a RecordComment explaining
the reason. In the long run, the reason should be an argument of
DeoptimizeIf, but we're not there yet.

On x87, things are a bit ugly due to some pushing/popping, so if
somebody feels inclined to improve this: Feel free. Probably the right
approach would be reloading instead of the push/pop horror.

Another thing is our inconsistent handling of the "done" continuation
of deferred code on the various platforms, I made tiny changes on the
way, but this should better be unified somehow, with all those
micro-optimizations removed.

a4176d2052 Removing ic.h from code-stubs.h 
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

More work could/should be done here, but this is a first step.

febf84a333 Added CallInterfaceDescriptors to all code stubs. A handful 
of code stubs are too complex to be described this way, and
they are encoded with the macro
DEFINE_NULL_CALL_INTERFACE_DESCRIPTOR().

Along the way:
* allowed inheritance of CallInterfaceDescriptors.
* Defined static Register methods for some of the new
  CallInterfaceDescriptors. We could go a lot further here, but
  it doesn't have to be done immediately.
* Added Representation arrays to some CallInterfaceDescriptors,
  especially where future hydrogen versions of the stubs could
  benefit from this knowledge.

d8295050d2 Fix deoptimization address patching in Turbofan to use safepoints. 
Since the deopt patch address needs to be available during GC to
resolve safepoints, we need to move it to the code object (instead of
the deoptimization input data) - accessing a separate fixed array
is not safe during GC. This CL adds a deoptimization_pc field to
each safepoint. The fields points to the deoptimization block.

The CL also fixes wrong register allocator constraints for
frame states on calls. These should always live on the stack
because registers are not preserved during a call.

6d3fc8a322 Introduce FLAG_vector_ics. 
When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs
will allocate a type vector slot to store feedback information. Full codegen
will emit a load of the slot into a register if the flag is on.

Support is incomplete, right now the IC doesn't know how to use the feedback
slot.

54636ae4e2 StubCallInterfaceDescriptor and CallInterfaceDescriptor are unified under a base class InterfaceDescriptor. 
Handling of the context register had to be massaged to effect the unification. This will make it easier to call hydrogen code stubs directly from crankshaft.

3d880be540 Use a register spec for StoreIC and KeyedStoreIC. 
This continues refactoring already applied for LoadIC in r22035 (https://code.google.com/p/v8/source/detail?r=22035).

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).
