77e53fc884 X87: Encapsulate megamorphic load/tail-call in hydrogen 
port r23772.

original commit message:

  To aid vector-based load ic work, we need to be able to handle
  the megamorphic load case in hydrogen. A simple approach is to
  wrap the probe activity in a hydrogen instruction.

  The instruction is novel in that it always tail-calls away.

  Refactoring InterfaceDescriptors away from code-stubs.h

  Clean up and create seperation between the concept of a call descriptor and a

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize(). 
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.

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.

f135cfa263 X87: Move function prototype handling into a special handler rather than IC 
port r22526.

original commit message:
  Move function prototype handling into a special handler rather than IC

  Adjust hydrogen handling of function.prototype to be based on map feedback.
  Handle non-instance prototype loading using an IC rather than in the hydrogen
  instruction. In the future, remove the special instruction and replace by multiple
  hydrogen instructions.

37ebdc7da5 X87: Introduce FLAG_vector_ics. 
port r22500.

original commit message:

  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.

23887bf978 X87: Clean up and update const / var 
port r22379

original commit message:
This CL simplifies var / const by ensuring the behavior is consistent in itself,
and with regular JS semantics; between regular var/const and eval-ed var/const.

Legacy const is changed so that a declaration declares a configurable, but non-writable, slot,
 and the initializer reconfigures it (when possible) to non-configurable non-writable. This
 avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects.
Undefined is used instead.
