7b9e24e3fb Clean up IC tracing for CallICs. 
CallICs have had some confused tracing, because the IC state is not
entirely captured by the installed code stub - it lives in the type
vector.

Change tracing to be able to use the vector state changes instead.
Introduced a DEFAULT state to be used by all vector-based ICs.

ae6496e6ea [Arm]: Optimize ConstantPoolBuilder::Populate code by minimizing calls to OffsetOfElementAt 
Calling OffsetOfElementAt becomes expensive when compiling functions with many
constant pool entries.  This was causing a regression in MandreelLatency due
to the time spent populating the constant pool array for large compiled
functions.

This change avoids calling OffsetOfElementAt for each entry, and instead keeps
track of the current offsets in ConstantPoolBuilder::Populate.  This gives the
following improvements on a Nexus 5:

                     Inline CP  |  OOL CP (before CL)  |  OOL CP (after CL)
Mandreel:               4305    |        3961          |       4120
MandreelLatency:        2298    |        1198          |       1994
Octane Score:           5197    |        4982          |       5152

OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and

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).

InitializeProperty only supports adding properties to extensible objects that do not contain the property yet. JSGlobalProxies cannot have properties themselves, so are not supported either.

1b080a76c1 [Arm] Various cleanups to the Arm assembler backend. 
A couple of cleanups to the Arm backend to enable support of extended
OOL constant pools in a following CL.

 - Remove instruction pattern extern const's and replace their use with IsXXX()
   functions.
 - Do calculation of the target address of a load from constant pool in one
   place.
 - A couple of other small cleanups.

7005abf03b Optimize Function.prototype.call 
- May inline the function, or call it directly, instead of going through call
- Supports arguments object escaping when it escapes to builtins (preparation for slice.call(arguments, ...) optimization)
- Both .call and .apply now support inlining when calling builtins indirectly
